24 October 1969: The Rescue of MISTY 11

by Captain Sean M. Cross, United States Coast Guard (Retired)

24 October 1969: During the Vietnam War from 1967–1972, eleven U.S. Coast Guard Aviators voluntarily served with high honor and distinction with the U.S. Air Force Aerospace Rescue and Recovery forces in Southeast Asia in the dual role of aircraft commanders and instructor pilots. They regularly risked their lives flying into harm’s way to save airmen in peril of death or capture. Their significant contributions and exceptional performance were highly commended by the Air Force with the award of four Silver Stars, sixteen Distinguished Flying Crosses, and eighty-six Air Medals, in addition to many other recognitions. The previous accolades did not come without cost —designated Coast Guard Aviator #997, Lieutenant Jack Columbus Rittichier was killed in action while attempting to rescue a downed Marine airman in hostile territory on June 9th, 1968. These Aviators carried out their noble mission with heroism and a focus on duty, honor, country and the Coast Guard. Their actions brought honor on themselves, the United States of America, the U.S. Air Force and the U.S. Coast Guard.

Interesting fact – of the roughly 200 Air Force Cross recipients, only 24 are enlisted rank, of which 12 are Pararescuemen (PJ). Nine PJs were awarded Air Force Crosses for Combat SAR missions in Vietnam…of those nine missions – two had Coast Guard Aviators as Aircraft Commanders – this is one (the other was the SCOTCH 3 mission involving LT Lance Eagan, USCG (CGA ’62) on 02 July 1968).

The goal of the combat rescue and recovery units was to get to those in peril before the enemy could capture of kill them. Whether the mission was an extraction or the pickup of a downed airman, each time they were successful it was a win. When it came to official Air Force data, this was labeled a “save,” but a “save” was much more than a statistic to these men. A “save” was a person, and they took it personally.

At Da Nang Air Base, Republic of Vietnam, the 37th Aerospace Rescue and Recovery Squadron (ARRS) was coming up on their 500th “save” in mid-October 1969. Everyone was looking forward to it. They arrived at number 497, then hit a dry spell for about a week. On 24 October, MISTY 11 went down and through a connected series of events, Coast Guard exchange pilots Lieutenant Richard Victor Butchka retrieved numbers 498, 499, and 500, and Lieutenant (j.g.) Robert T. Ritchie claimed numbers 501 and 502.

Similar to MISTY 11, this North American Aviation F-100F-10-NA Super Sabre, 56-3837, was also a FastFAC. It is in the collection of the National Museum of the United States Air Force, Wright-Patterson AFB, Ohio. (U.S. Air Force)

Northeast of Saravane, Laos, MISTY 11, a U.S. Air Force North American Aviation F-100F Super Sabre “Fast FAC”—a jet Forward Air Controller) was designating targets along the Ho Chi Min Trail for ground interdiction strikes when it experienced engine failure due to antiaircraft fire. The stricken aircraft quickly descended to less than 1,000 feet (305 meters) above the terrain. The approximate time was 8:00 a.m. A MAYDAY was broadcast and the two crewmen ejected at low altitude. They parachuted into the jungle-covered mountainous terrain. MISTY 11 Alpha, 1st Lieutenant Alvin Donald Muller, and MISTY 11 Bravo, Captain Jack K. Clapper, were separated by about 800 yards (732 meters) due to the programmed delay in the ejection sequence between the front and rear ejection seats.

The survivors’ position was in a small valley formed by two ridges about 100 meters long oriented north and south. At the north end where the ridges joined, a road was cut 20 meters from the top of the hill. MISTY 11A was on the east side of the valley and MISTY 11B was on the west side.

Area of operation.

Each was equipped with a battery-powered radio and was contacted by an airborne Forward Air Controller (FAC), a North American Aviation OV-10A Bronco, NAIL 07, who had heard their pre-ejection call and was working in the area. The FAC said that he would notify Search and Rescue. MISTY 11A (Muller) informed MISTY 11B and the FAC that his leg was badly broken. MISTY 11B (Clapper) was unhurt.

Less than two hours from notification, two Douglas A-1 Skyraiders—call signs SANDY 11 and 12—and two Sikorsky HH-3E Jolly Green Giant helicopters—JOLLY 28 and 04—from strip alert in Quang Tri were on scene.

JOLLY 28 (HH-3E #66-13280) crew members: Captain Charles D. Langham, USAF (Pilot); Major Charles W. Bond (Co-Pilot); Staff Sergeant James E. Smith (Flight Engineer); and Technical Sergeant Donald G. Smith (Pararescueman)

JOLLY 04 (HH-3E #66-13290) crew members: Lieutenant Richard Victor Butchka, USCG (Pilot); Captain John K. Coder, USAF (Co-Pilot); Sergeant Joseph J. Vai (Flight Engineer); and Airman 1st Class George P. Hoffman III (Pararescueman)

The helicopters went into orbit. One Jolly Green, referred to as the “low bird,” would make the rescue attempt while the second, the “high bird,” would remain in a 3,000-foot (914 meters) orbit as backup. Before sending in JOLLY 28, the two A-1s trolled the area, but their repeated passes brought no response from enemy ground-fire. It was determined that Muller should be rescued first because of his broken leg and at about 11:00 a.m., JOLLY 28 descended toward MISTY 11A.

The terrain in the SAR area was rolling foothills with elevations varying from 1,500 feet MSL (Mean Sea Level: describes height above standard Sea Level) in the ravines, to 2,500 feet MSL on the hilltops (500 to 833 meters). The vegetation on these hills varied from dense triple-layered canopy jungles to open areas with tall jungle grass. The entire immediate area around MISTY 11A and B was defended by heavy small arms and automatic weapons as close as 50 feet to the survivors. The proximity of hostile forces to the survivors severely restricted the type of ordnance which could be delivered to protect them. There were scattered variable broken cumulus build-ups in the area with tops to 9,500 feet MSL and bases varying from 2,000 to 3,000 feet AGL (Above Ground Level: describes height above the ground). Visibility below the clouds was excellent.

Lieutenant Butchka, in the “high bird,” JOLLY 04, watched his good friend, Captain Charles Langham, descend for the recovery. JOLLY 28 entered a hover over MISTY 11A and lowered the “PJ,” Don Smith, by hoist. The PJ immediately had the downed airman on the canopy penetrator and gave the cable-up signal. Less than a minute had elapsed. When the penetrator was approximately 10 feet off the ground, the helicopter came under attack.

Butchka saw three sides of the blind canyon twinkling. It appeared that enemy forces had used the downed F-100F crewman as bait for a “flak trap.” The Skyraiders rushed in to suppress the fire, but the opening enemy volley had shot the hoist assembly off its mounts, sending it crashing into the flight engineer’s chest and dumping the PJ and MISTY 11A back on the ground. Realizing the hoist was inoperative, the flight engineer, SSGT James Smith, hit the switch shearing the hoist cable and yelled to Captain Langham to transition JOLLY 28 to forward flight.

Above, Butchka punched off his auxiliary fuel tanks and went into a plunging autorotative descent. Seeing Langham’s aircraft smoking and streaming fluid (was hit in the main gearbox and was losing oil pressure), Butchka told him to put the helicopter on the ground. Langham searched for a clear spot and put the aircraft into a small punch bowl-shaped valley. Langham and crew jumped out of the helicopter into the elephant grass, looking up for high bird. They did not have far to look. Butchka’s helicopter was in a 25-foot hover on the left side of Langham’s helicopter with its hoist cable waiting. Butchka expected ground fire from the enemy at any moment. During the swift pick up, the helicopter shuddered with a jolt to the right side. The aircraft’s skin was holed with a gash eight inches long by two inches wide.

Major Charles W. Bond had the honor of being the 500th save.

With the men safely on board, the next problem was getting out of there. Butchka did not want to go back out the way he came because of heavy enemy fire. Weather was hot and humid, pressure altitude was high, and the only other way out presented him with a vertical face rising about 130 feet. It was decision time. Butchka said; “I headed for the face, pulled every bit of power I could (‘pulled the collective to my arm pit’ was the description in another interview), and with a little bit of airspeed drooped the rotor to 94-percent — and just cleared the top.” As he eased over the ridgeline, the JOLLY immediately came under heavy ground fire from a different direction. SANDY lead hadn’t reported anything because he didn’t know where Butchka was. Miraculously they were not hit. However, JOLLY 04 “caught his blades in some trees and is requesting escort out of the area.” A forward air controller, COVEY 297, escorted JOLLY 04 to Lima Site 61, an Air Force TACAN navigation site at Muang Phalan, Laos.

There were still two MISTY crewmembers and Langham’s PJ on the ground at the initial recovery spot. The PJ, Technical Sergeant Donald G. Smith, using his handheld radio, reported “contact with bad guys 35 meters to my west” and directed air strikes bracketing their position. JOLLY 76, a Sikorsky HH-53C Super Jolly Green Giant from the 40th ARRS at Udorn, Thailand, made three recovery attempts but each time received intense ground fire resulting in extensive battle damage to the helicopter. JOLLY 76 sustained severe battle damage, loss of hydraulic systems and associated tail rotor control problems that forced the aircraft to withdraw. JOLLY 76 was escorted out of the area by JOLLY 72 and A-1s SANDY 01 and  04, and successfully recovered at Lima Site 44, an unimproved covert landing strip near Saravane, Laos.

Later that afternoon the JOLLIES tried again. After multiple A-1 passes dropping CBU-19s ( a 130-pound modified dispenser containing 528 canisters with an incapacitating chemical CS—”tear gas”) SANDY 06 and 05 escorted “low bird” JOLLY 15 with Coast Guard Lieutenant (j.g.) Rob Ritchie into the rescue area.

Rob said; “The previous attempts that day were all into the wind approaches. I chose a downwind approach because all indications were the ‘bad guys’ were set up for us to come into the wind and were waiting.” The SANDYs made suppression runs and laid smoke as had been requested – then they joined in a daisy chain of passes that provided protective fire. Ritchie used the smoke for cover, swooped in fast and quickly put the aircraft into a hover over Smith and MISTY 11A. TSgt. Gaydos fearlessly operated the rescue hoist while completely exposed to the hostile fire impacting about him. His reassuringly calm hover instructions to the pilots, ensured Smith and MISTY 11A were quickly brought on board with only slight damage to the aircraft. During Ritchie’s next approach to pick up MISTY 11B they began taking very heavy ground fire on the way in. The element of surprise was no longer there and the North Vietnamese had repositioned. SANDY Lead called the approach off and both A-1s made several suppression runs.

Ritchie commenced his third approach immediately after the suppression runs. He said it was much quieter this time and he came to a hover over MISTY 11B. As the penetrator went down the ground fire became much heavier and the helicopter was taking numerous hits. The utility hydraulics to the hoist was disabled due to ground fire damage to a pressure line and fluid flow was lost. Unable to complete the pickup Ritchie exited the area. JOLLY 15 notified SANDY 03 that he would be unable to remain in the area and commenced a rendezvous for air refueling with KING 03, a Lockheed C-130 Combat King. JOLLY 15 landed at Lima Site 61  at 3:35 p.m.

Two additional tries to pick up MISTY 11B were made to no avail. A tropical thunderstorm moved in and heavy rain fell for the next 30 minutes. A third attempt was made while the squall was passing through and as the storm began to subside, the winds became relatively calm and the previously laid smoke screen began to envelope the area – adversely impacting the rescue helicopters’ visibility and making it more difficult to locate MISTY 11B.

Fortunately, the survivor’s emergency radio was operational and the pilot knew how to use it. By coordinating voice guidance from MISTY 11B on the ground and SPAD 09 (circling overhead), JOLLY 19, another HH-3E, flew over Clapper and lowered a canopy penetrator to him. He climbed onto the device and the helicopter quickly exited the area as soon as Clapper was clear of the trees. The gunner on the rescue helicopter pulled him in the door and the MISTY 11 rescue was successfully concluded at around 6:00 p.m.

Epilogue: For their efforts during this combat rescue the following medals were awarded:

Master Sergeant Donald G. Smith, United States Air Force.

Technical Sergeant Donald G. Smith, USAF, Pararescueman from JOLLY 28 was awarded  the Air Force Cross:

The President of the United States of America, authorized by Section 8742, Title 10, United States Code, awards the Air Force Cross to Technical Sergeant Donald G. Smith for extraordinary heroism in military operations against an opposing armed force as a Pararescueman on a HH-3E Rescue Helicopter in Southeast Asia on 24 October 1969. On that date, Sergeant Smith voluntarily descended to the surface on a forest penetrator to assist a downed pilot. As he and the pilot were being raised, hostile fire rendered the hoist inoperative and the cable was sheared, dropping them fifteen feet to the ground. Sergeant Smith’s position was surrounded by hostile forces, and his helicopter was downed by hostile fire. Remaining exceptionally calm, his resolute and decisive presence encouraged other survivors, while his resourcefulness in controlling and directing the aircraft providing suppressive fire, resulted in the safe recovery of all downed personnel. Through his extraordinary heroism, superb airmanship, and aggressiveness in the face of the enemy, Sergeant Smith reflected the highest credit upon himself and the United States Air Force.

Lieutenant Robert T. Ritchie, USCG, was awarded the Silver Star.

The President of the United States of America takes pleasure in presenting the Silver Star (Air Force Award) to Lieutenant, Junior Grade, Robert T. Ritchie, United States Coast Guard, for gallantry in connection with military operations against an opposing armed force while attached to the 37th Aerospace Rescue and Recovery Squadron (USAF). Lieutenant, Junior Grade, Ritchie distinguished himself as Aircraft Commander of an HH-3E rescue helicopter in Southeast Asia on 24 October 1969. On that date, Lieutenant, Junior Grade, Ritchie repeatedly penetrated an area of intense hostile fire in an effort to rescue three downed airmen before battle damage rendered his aircraft incapable of further rescue operations. By his gallantry and devotion to duty, Lieutenant, Junior Grade, Ritchie has reflected great credit upon himself and the United States Air Force.

CPT Charles D. Langham Silver Star medal ceremony

Captain Charles D. Langham, USAF, earned the Silver Star:

Captain Charles D. Langham distinguished himself by gallantry in connection with military operations against an opposing armed force as Aircraft Commander of an HH-3E helicopter in Southeast Asia on 24 October 1969. On that date, while attempting to recover two downed Air Force pilots., Captain Langham’s aircraft was subjected to intense hostile fire. Displaying superb airmanship, Captain Langham nursed his critically damaged aircraft way from the immediate hostile area and effected an emergency landing in a confined, remote area which saved his crew from probable serious injury or possible death. By his gallantry and devotion to duty, Captain Langham has reflected great credit upon himself and the United States Air Force.

LT Richard V. Butchka, USCG, earned the Distinguished Flying Cross with Combat V.

The President of the United States of America takes pleasure in presenting the Distinguished Flying Cross with Combat “V” (Air Force Award) to Lieutenant Richard V.

26 September 1971: This Day in Coast Guard Aviation History

by Captain Sean M. Cross, United States Coast Guard (Retired)

During the Vietnam conflict from 1967–1972, eleven U.S. Coast Guard Aviators voluntarily served with high honor and distinction with the U.S. Air Force Aerospace Rescue and Recovery forces in Southeast Asia in the dual role of aircraft commanders and instructor pilots. They regularly risked their lives flying into harm’s way to save airmen in peril of death or capture.

Manion (Pararescue Jumper) and Richard L. Steed (Pararescue Jumper), rescued the crew of a North American Aviation OV-10A Bronco (call sign “RUSTIC 07″), Lieutenant Lansford Elmer Trapp, Jr., and Cambodian observer, Sergeant Chap Khorn, after they ejected from their 12.7mm-damaged aircraft, about 10 miles (16 kilometers) northwest of Kampong Cham, Cambodia.

To better cover the southern portion of South Vietnam and be closer to the increasing levels of operations in Cambodia, the 37th Aerospace Rescue and Recovery Squadron (ARRS) had for some time maintained a pair of HH-53Cs at Bien Hoa Air Base, about fifteen miles northeast of Saigon.  On September 26, 1971, it was Coast Guard exchange pilot Lieutenant Commander Joseph “Jay” Crowe’s turn to stage at the forward operating location (FOL). Standing the alert with his crew, Hampton, Simm, Manion, and Steed, they were scrambled to rescue of the crew of an OV-10A from the 19th TASS who shared the ramp at Bien Hoa.

The Rustic FAC, the call sign that any FAC [Forward Air Controller] operating in Cambodia used, regardless of squadron, had fallen victim to a “.50-caliber trap” when it was hit at 3,500 feet (1,067 meters) by converging fire from four 12.7mm AA machine guns ringing the perimeter of a small village about ten miles (16 kilometers) northwest of the Mekong River town of Kampong Cham. When grouped as a battery, the 12.7 mm guns, “heavy guns” of the southern air war (where the heavy AA weapons of Laos and North Vietnam had not yet appeared in large numbers), were still quite deadly. The Bronco pilot, 1st Lieutenant Lansford Trapp, and his observer, Cambodian Sgt. Chap Khom, had parachuted down into the apex of the gun formation, and the hostile forces accompanying the AAA gunners were in no rush to go get them.

In an interview with his grandson recorded in 2018, retired General Lansford E. Trapp described the incident:

“When I was a lieutenant, and this would have been in 1971, I was flying an observation aircraft over in Vietnam. I was on a mission over in Cambodia and we were helping ground forces who were fighting against bad guys over there. That ensuing battle that went on as I was flying over head in my airplane, we actually got hit by ground fire and the left wing of the airplane caught on fire.

“I had a Cambodian interpreter sitting in my back seat, a Sergeant Chung (Khorn), and it was his seventh ride in an airplane. I didn’t even know that the wing was on fire until one of the other airplanes came by and said “hey your left wing is on fire”. So, I looked out, my wing was on fire, and we decided that I was gonna be able to land at one of the airports that was right there. So, we came in and tried to land, but I lost control of the airplane. So, I pushed the power back in and climbed up over the airfield. Then the left wing burned off, and so we started in a pretty good spiral into the wing that had burned off. We ejected from the airplane.

“Sergeant Corn (Khorn) went out first, and then I went out. The craziest thing was that we used to fly with about 250 to 300 big maps, so we could look at the country as we were trying to figure out where we were. Those all came flying out of the cockpit as we ejected. It looked like confetti outside. As we came down sergeant Corn he got burned pretty bad from the wing fire, and I banged my ankle up pretty badly, but we were OK. We got picked up by friendly forces and I got a nice helicopter ride back to home base that night.”

Crowe’s Jolly approached at 8,000 feet (2,438 meters), safely above the range of the still-active hostile guns, while the A-1H Sandys of the 1st Special Operations Squadron (SOS) went in low to begin their routine of locating the survivors and the hostile guns. In the flat and relatively open terrain of central Cambodia, penetrating the ring of guns was going to be dicey, there not being the ridges, karsts, and dense vegetation of the 37th’s regular operating area to provide a modicum of masking for the helicopter. By this stage of the war, a low, treetop-hugging approach by the rescue helicopter was a well-known procedure, and the enemy gunners would be waiting for it, scanning the low horizon for the rescue helicopter sure to follow on the heels of the tough Skyraiders. Each gun guarded its quadrant of the circle around the downed airmen, waiting.

Crowe decided to use a variation of the diving spiral approach he had used June 4th with success, rescuing a Covey FAC crew up in southern Laos. Rather than descending some distance away prior to a low-level run-in, he entered an autorotation from directly overhead, copilot Hampton pulling the throttles of the twin engines back, and Crowe lowering the collective stick. Down the helicopter fell, with the rush of air up through the rotors keeping the blades spinning, while the engines idled (relatively quietly). The blades are unloaded in an autorotative descent, so the characteristic whop-whop is virtually eliminated, and with the engines at idle, there is significantly less of the distinctive noises that normally come from the helicopter.

With the Sandys rumbling around, strafing and bombing and attracting the eye of the gunners, the diminished but still telltale sounds made by the falling Jolly were masked.  Crowe kept the helicopter in a steep turn, spiraling down inside the perimeter of the four guns around the downed aircrew, literally behind their backs, careful not to swing out too wide, where he might catch a gunner’s eye. The Jolly would be easily seen should anyone glance straight up, luckily the last place a sane gunner would be looking for a helicopter.  They were falling out of the sky at more than five thousand feet per minute. As the Jolly approached the ground, Crowe began to level off, converting vertical speed to speed across the ground, still spiraling, and then raised the nose to decelerate.

HH-53C (VIRIN: DF-ST-83-02388)

At the same time, Hampton slowly and smoothly pushed the engine throttles forward, to accelerate them back into normal speed and gently engage their drive wheels with the spinning gears of the main rotors. The accelerating engines and the rotors digging into the air as Crowe pulled up on the collective and flared into a quick-stop created loud rotor beats, accenting the whine of jet turbines accelerating to maximum power, announcing their arrival to all. But the helicopter was safely down beneath the trees in a hover, and the telltale was too late to help the gunners acquire their target. This tight spiral autorotative descent and recovery to a hover requires a superior feel for the helicopter, and exquisite coordination with the copilot to return the rotors to engine-driven flight smoothly at just the right instant. Done right, the procedure is a dramatic and breathtaking maneuver and a grand entrance. But the room for error is very small, and a botched maneuver is perilous and very unforgiving.

It was not a gambit to be repeated very often; if the gunners had detected the helicopter, Crowe and company would have found themselves in a deadly crossfire. But this day it was brilliant: a tactical surprise, completely unexpected, and therefore completely effective. The Jolly crew snatched the two men quickly and escaped out of the circle with a low-level departure. A climbing spiral back up from the center of the guns, with the gunners now alerted, was clearly out of the question. The helicopter received only sporadic fire as it left the scene in the typical low-level escape, while taking no casualties.
