26 September 1927: Flight Lieutenant Sidney Norman Webster, of the Royal Air Force High Speed Flight, won the 1927 Schneider Trophy Race, flying a Supermarine S.5 float plane, number N220.

The course consisted of seven laps of a 50-kilometer course at Venice, Italy. Webster completed the race in 46 minutes, 20.3 seconds, averaging 281.656 miles per hour (453.281 kilometers per hour). He established a new Fédération Aéronautique Internationale (FAI) World Record for Speed Over 100 Kilometers. (FAI Record File Number 11070.)

Webster’s teammate, Flight Lieutenant Oswald Worsley, flying S.5 N219, placed second with a time of 47:46.7 and average speed of 272.91 miles per hour (439.21 kilometers per hour).

The Supermarine S.5 was designed by Reginald Mitchell, who would later design the famous Supermarine Spitfire fighter. N220 was a single-place, single-engine, low-wing monoplane equipped with pontoons for landing and taking off on water. The airplane was of all metal construction, primarily duralumin (a hardened alloy of aluminum and copper). The airplane used surface radiators in the skin of the wings for engine cooling. It had a length of 24 feet, 3½ inches (7.404 meters), wingspan of 26 feet, 9 inches (8.153 meters) and height of 11 feet, 1 inch (3.378 meters). The S.5’s empty weight was 2,680 pounds (1,216 kilograms) and gross weight was 3,242 pounds (1,471 kiograms).

Webster’s Supermarine S.5 was powered by a water-cooled, naturally-aspirated 1,461.135-cubic-inch-displacement (23.943 liter) Napier Lion Mk.VIIB, serial number 63106, a double-overhead camshaft (DOHC) twelve-cylinder engine with three banks of four cylinders. This was called a “W-12” or “broad arrow” configuration. The Mk.VIIB had a 10:1 compression ratio and produced 875 horsepower at 3,300 r.p.m. It drove a two-bladed propeller through a gear reduction unit. (Worsley’s Supermarine S.5 N219 was equipped with a 900 horsepower direct-drive Mk.VIIA.) The engine used a mixture of 75% gasoline, 25% benzol, and tetraethyl lead. The Napier Lion Mk.VII was 5 feet, 6¼ inches (1.683 meters) long, 3 feet, 2½ inches (0.978 meters) wide and 2 feet, 10½ inches (0.876 meters) high. The geared Mk.VIIB was heavier than the direct drive Mk.VIIA, and weighed 920 pounds (417 kilograms).

The Supermarine S.5 had a maximum speed of 319.57 miles per hour (514.3 kilometers per hour).

“Webbie” Webster had been awarded the Air Force Cross in 1922. He received a second award, 11 October 1927:

The King has been graciously pleased to approve the award of a Bar to the Air Force Cross held by Flight Lieutenant Sidney Norman Webster, AFC, in recognition of his achievement winning the recent “Schneider Cup” Air Race.

In January 1946, Air Commodore Webster was appointed Commander of the Most Excellent Order of the British Empire. He was promoted to Air Vice Marshal in 1949 and retired from the Royal Air Force 12 August 1950.

Air Vice Marshal Sidney Norman Webster, CBE, AFC and Bar, Royal Air Force, died 5 April 1984 at the age of 83 years.

25 September 1978, 16:02:07 UTC

PSA Flight 182, on fire after mid-air collision, 25 September 1978. (Hans Wendt, County of San Diego)

25 September 1978: At 09:02:07 a.m., local time, the worst aircraft accident in California history occurred when a Boeing 727-214 airliner, civil registration N533PS, operated by Pacific Southwest Airlines (PSA) as Flight 182, crashed at the intersection of Dwight Street and Nile Street in the North Park neighborhood of San Diego, 4,830 meters (3.00 miles) northwest of Lindbergh Field (SAN), today known as San Diego International Airport.

Flight 182 was a regularly scheduled commercial airline flight from Sacramento, California to San Diego, with a stopover at Los Angeles. Captain James E. McFeron, a 17-year veteran of PSA, was in command. First Officer Robert E. Fox was the pilot flying the 727 on this leg. The Flight Engineer (also called the Second Officer) was Martin J. Wahne. Also in the cockpit, occupying the two “jump seats” were two off-duty PSA captains. Four flight attendants were on duty in the passenger cabin along with 126 passengers, which included 30 PSA employees.

In clear weather and early morning sunlight, the airliner was on an visual approach to Lindbergh. The 727 passed over the Mission Bay VORTAC (MZB), a navigation aid 3.4 miles (5.5 kilometers) northwest of the airport, and turned left to a heading of 090° to intercept the downwind leg of the approach.

Ahead of the 727, a single-engine light airplane, a Cessna 172, N7711G, with an instructor and student aboard, had made two practice ILS approaches to Runway 9 at Lindbergh and departed to the northwest, returning to its base at Montgomery Field (MYF), 6.4 miles (10.3 kilometers) north-northeast of SAN.

Approach Control called, Cessna 7711G, radar contact, maintain VFR at or below 3500 [1,067 meters], fly heading 070, vector (for) final approach course.” The pilot of the Cessna, David T. Boswell, acknowledged the east-north-easterly heading and the altitude restriction. About 15 seconds later, at 08:59:39, the controller informed the 727, “Additional traffic’s twelve o’clock, three miles, just north of the field, northeastbound, a Cessna One Seventy-Two climbing VFR out of one thousand four hundred.” [427 meters] At 08:59:50, First Officer Fox reported, Okay, we’ve got that other twelve.”

Radar tracks show that N7711G initially maintained the assigned heading but after about one minute, turned 20° right to 090°, the same heading as that of Flight 182.

At 09:00:23, Approach Control acknowledged Flight 182: “Okay, sir, maintain visual separation, contact Lindbergh Tower 133.3. Have a nice day, now!”

Flight 182 switched radio frequencies and Captain McFeron checked in with the tower: “Lindbergh, PSA 182. Downwind.” The Tower Controller responded, “PSA 182, Lindbergh Tower, traffic 12 o’clock, one mile, a Cessna.”

In the cockpit there was confusion about the reported conflicting traffic ahead. Captain McFeron asked, “Is that the one we’re looking at?” Flight Engineer Wahne replied, “Yeah—but I don’t see him now.” McFeron called the Tower, “Okay, we had it there a minute ago.” The Controller replied, “One Eighty-Two, roger.” The Captain continued, “I think he’s passed off to our right.”

Inside the cockpit, McFeron said, “He was right over there a minute ago.” Wahne agreed, “Yeah.”

Lindbergh Tower authorized Flight 182 to land, “PSA 182—cleared to land,” and McFeron acknowledged with, “PSA 182’s cleared to land.” He then asked the Flight Engineer, “Are we clear of that Cessna?” Wahne said, “Supposed to be!” McFeron responded, “I guess.” In the cockpit’s jump seat, one of the two off-duty captains said, “I hope!”

At 09:01:21, Captain McFeron stated, “Oh, yeah, before we turned downwind, I saw him about one o’clock, probably behind us now.”

First Officer Fox called for the wing flaps to be lowered and then at 09:01:31 he asked for the landing gear to be lowered. At 09:01:38, Fox said, There’s one underneath [pause] I was looking at that inbound there.” Flight 182 was now descending through 2,600 feet (793 meters).

At 09:01:47, the Flight 182’s Cockpit Voice Recorder picked up the sound of the collision.

The Boeing 727 struck the Cessna 172 from above and behind, destroying it. The airliner was heavily damaged and on fire. With the flight controls damaged, Flight 182 rolled and turned to the right. On a heading of approximately 200°, it crashed into residential neighborhood in a 300 mile per hour (483 kilometers per hour), 50° dive.

According to seismographs at the Museum of Natural History, San Diego, the impact occurred at 09:02:07 a.m., Pacific Daylight Savings Time (16:02:07 UTC).

The largest piece of the Cessna impacted six blocks away, near 32nd Street and Park Avenue.

All 135 persons aboard the 727, both persons on the Cessna, and seven persons on the ground were killed. Another nine persons on the ground were injured. Twenty-two homes in a four-block area were destroyed or damaged.

The last words of the flight deck personnel recorded by the Cockpit Voice Recorder were that of an unidentified voice saying, “Ma, I love you.”

The Pilot in Command of Flight 182, Captain James E. McFeron, had been employed by Pacific Southwest Airlines since 1961. He held an Airline Transport Pilot Certificate and was type-rated in both the Lockheed L-188 Electra and the Boeing 727. He had a total of 14,382 flight hours, with 10,482 hours in the Boeing 727.

First Officer Robert E. Fox, Jr., also held an ATP certificate. Of his 10,049 flight hours, 5,800 were in the 727. He had been with PSA for 9 years.

Flight Engineer Martin J. Wahne had worked for PSA for 11 years. He had 10,800 hours, with 6,587 hours in the Boeing 727.

The Pilot in Command of the Cessna was Gunnery Sergeant David Lee Boswell, U.S. Marine Corps, who was stationed at Camp Pendleton, north of San Diego. Gunnery Sergeant Boswell held Commercial Pilot and Flight Instructor certificates, with Airplane—Single– and Multi–Engine Land ratings. He was receiving instrument flight instruction to apply for an Instrument Rating. Boswell had 407 total flight hours, and had flown 61 hours in the previous 90 days.

The Instructor Pilot on board the Cessna was Martin B. Kazy, Jr., an employee of the aircraft owner, Gibbs Flight Center at Montgomery Field. He held Commercial Pilot and Flight Instructor certificates, with Airplane Single– and Multi–Engine Land, and Instrument–Airplane ratings. He had a total of 5,137 flight hours. Kazy had flown 347 hours in the previous 90 days.

The aircraft operated as PSA Flight 182 was a Boeing 727–214, serial number 19688, which made its first flight 4 June 1968. At the time of the accident, the total time on the airframe (TTAF) was 24,088.3 hours. It had made 36,557 takeoffs and landings.

The Boeing 727–200 series was a stretched version of the original –100 model. It was designed to be operated by a flight crew of three, and could carry up to 189 passengers. The –200 was 153 feet, 2 inches (46.685 meters) long with a wingspan of 108 feet, 0 inches (32.918 meters) and overall height of 34 feet, 0 inches (10.363 meters). The empty weight was 98,400 pounds (44,633 kilograms) and maximum takeoff weight (MTOW) was 184,800 pounds (83,642 kilograms). The airliner was powered by three Pratt & Whitney JT8D-9 low-bypass axial-flow turbofan engines, rated at 14,500 pounds of thrust at Sea Level for takeoff (5-minute limit), and 12,600 pounds of thrust, maximum continuous power. This gave the 727–200 a maximum cruise speed of 0.9 Mach (610 miles per hour, or 982 kilometers per hour, at 30,000 feet/9,144 meters). Its service ceiling was 42,000 feet (12,802 meters), and the maximum range was 1,956 miles (3,148 kilometers).

1,832 727s were built by Boeing between 1963 and 1984. 1,245 of these were 727-200s.

25 September 1960: At Edwards Air Force Base, California, Commander John F. Davis, United States Navy, flew a McDonnell F4H-1 Phantom II to a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a Closed Circuit of 100 Kilometers Without Payload, averaging 2,237.37 kilometers per hour (1390.237 miles per hour). Commander Davis flew the 62-mile circular course at an altitude of 45,000 feet (13,716 meters).

“On 25 September 1960 Davis flew the shorter, 100-kilometer course at 1,390.24 miles per hour, roughly Mach 2.2. He went around the course in a continuous circle, at 70° of bank and three g’s. The heavy bank put the honeycomb structure of the right stabilator directly in the engine exhaust the entire way around, but it held on. These two flights demonstrated the brute strength of the airframe and the sophistication of the F4H navigation system around the curves.”

The planned flight was from Moscow to Komsomolsk-on-Amur. In adverse weather conditions, they missed the airfield at Komsomolsk, and out of fuel, crash landed in a forest near the Sea of Okhotsk. Raskova was ordered to bail out of the airplane and wandered for ten days before she located the crashed ANT-37. The other two remained with the ANT-37 and survived the landing. They waited by the wreck for Raskova. All three were made Heroes of the Soviet Union.

The three women were all highly experienced aviators and each held multiple world records. (Grizodubova held one FAI altitude record, two distance and three speed; Osipenko held three distance and three altitude records; and Raskova was a navigator on two distance record flights.)

Polina Osipenko was killed in an airplane accident in 1939. Marina Raskova died when her bomber crashed in 1943. She received the first state funeral of the war. Valentina Grizodubova survived World War II and then served on a commission investigating Nazi war crimes.  She died at Moscow in 1993.

The Antonov ANT-37, given the military designation DB-2, was a prototype long range medium bomber designed and built at Tupolev OKB. The design team was led by Pavel Sukhoi.

Rodina, the airplane flown by Grizodubova, Osipenko and Raskova, was the first prototype ANT-37. It had crashed during testing 20 July 1935, but was rebuilt as the ANT-37 bis, or DB-2B. The nose section was modified and the engines and propellers upgraded, all military armament was removed and larger fuel tanks installed. It was powered by two 2,359.97-cubic-inch-displacement (38.67 liter) air-cooled, supercharged, Tumansky M-86 two-row, 14-cylinder engines producing 950 horsepower at 2,250 r.p.m. for takeoff and driving three-bladed, variable pitch propellers. (These engines were license-built versions of the Gnome et Rhône 14K Mistral Major.) The main landing gear was retracted by electric motors.

The airplane was operated by a crew of three. It was 15.00 meters (49 feet, 2.6 inches) long with a wingspan of 31.00 meters (101 feet, 8.5 inches). Its empty weight was 5,855 kilograms (12,908 pounds) and gross weight was 12,500 kilograms (27,558 pounds). The maximum speed was 300 kilometers per hour at 0 meters (186 miles per hour at Sea Level) and 342 kilometers per hour (212.5 miles per hour) at high altitude. The service ceiling was 8,000 meters (26, 247 feet).
