22 November 1972: The Boeing B-52 Stratofortress bombers began combat operations in the Vietnam War with ARC LIGHT strikes against enemy troop concentrations and supply lines in June 1966. The B-52s flew so high and fast that they could neither be seen nor heard on the ground. It was more than six years before the first of the eight-engine bombers would be lost to enemy action.

B-52D-65-BO 55-0110, call sign OLIVE 2, was assigned to the 96th Bombardment Wing, Heavy. It flew combat missions from Andersen Air Force Base, Guam, and the U-Tapao Royal Thai Navy Airfield, Thailand. On 22 November, -110 was crewed by Captain Norbert J. Ostrozny, aircraft commander; Captain P. A. Foley, co-pilot; Bud Rech, radar navigator; Captain Robert Estes, navigator; Larry Stephens, electronic warfare officer; and Staff Sergeant Ronald W. Sellers, gunner.

Near Vinh, on the central coast of North Vietnam, OLIVE 2 was struck by an exploding S-75 Dvina surface to-air missile (NATO identified the S-75 as the SS-2 Guideline, commonly referred to as a SAM). The S-75 is a Soviet two-stage command-guided surface-to-air anti-aircraft missile. It is 10.60 meters (34 feet, 9.3 inches) long and 0.7 meter (2 feet, 3.6 inches) in diameter. It is liquid-fueled and has a maximum speed of Mach 4 and range of 24 kilometers (15 miles). The missile has a 200 kilogram (441 pound) fragmentation warhead. The loaded weight is 2,300 kilograms (5,071 pounds).

OLIVE 2 was seriously damaged and on fire, and the flight crew turned toward the airfield at U-Tapao.

After crossing the Thailand border, Captain Ostrozny ordered the crew to eject from the stricken bomber. All six crewmen escaped the doomed Stratofortress and were later rescued by a Sikorsky HH-53 Super Jolly Green Giant search-and-rescue helicopter.

55-0110 crashed 15 miles (24 kilometers) southwest of Nakhon Phanom, Thailand. It was the first Stratofortress lost to enemy action in more than six years of combat.

The United States Air Force flew more than 125,000 combat sorties with the B-52 from 1966 to 1973. During that time, the bombers delivered 2,949,615 tons of bombs against enemy targets. A total of 31 B-52s were lost. 73 crewmen were killed in action and 33 captured and held as prisoners of war.

14 October 1962: Major Richard Stephen (“Steve”) Heyser, a pilot with the 4028th Strategic Reconnaissance Squadron, 4080th Strategic Reconnaissance Wing, United States Air Force, boarded Item 342, his Top Secret reconnaissance airplane, at Edwards Air Force Base, California. Over the next seven hours he flew from Edwards to McCoy AFB, near Orlando, Florida, landing there at 0920 EST.

But first, Steve Heyser and Item 342 flew over the island of Cuba at an altitude of 72,500 feet (22,098 meters). Over the island for just seven minutes, Heyser used the airplane’s cameras to take some of the most important photographs of the Twentieth Century.

Item 342 was a Lockheed U-2F. Designed by Clarence L. (“Kelly”) Johnson at the “Skunk Works,” it was a very high altitude, single-seat, single-engine airplane built for the Central Intelligence Agency. Item 342 carried a U.S. Air Force number on its tail, 66675. This represented its serial number, 56-6675.

It had been built at Burbank, then its sub-assemblies were flown aboard a C-124 Globemaster transport to a secret facility at Groom Lake, Nevada, called “The Ranch,” where it was assembled and flown.

Originally a U-2A, Item 342 was modified to a U-2C, and then to a U-2F, capable of inflight refueling.

Major Heyser had been at Edwards AFB to complete training on the latest configuration when he was assigned to this mission.

Major Heyser’s photographs showed Russian SS-4 Sandal intermediate range nuclear-armed missiles being placed in Cuba, with SA-2 Guideline radar-guided surface-to-air anti-aircraft missile sites surrounding the nuclear missile sites.

President John F. Kennedy ordered a blockade of Cuba and demanded that Russia remove the missiles. Premier Nikita Khrushchev refused. The entire U.S. military was brought to readiness for immediate war. This was The Cuban Missile Crisis. World War III was imminent.
