역사 1952년 - 토네이도가 기지를 강타해 SAC가 보유한 B-36의 2/3가 손상

[위종민]

1948년 운영되기 시작한 B-36은 1952년 9월 1일 텍사스 중북부를 강타한 토네이도로 당시 보유기의 2/3에 달하는 83기를 손실했다고 합니다. 근무인원 부족으로 강철케이블 고정 조치만 취했는데, 측정풍속 최대 시속 90마일(=40m/s)에 달하는 강풍으로 한 대는 완전손실, 유도로에 있던 72대도 파손으로 비행하지 못했고 컨베어사 공장에 주기돼 있던 10대도 파손됐네요. 

다음날부터 1쪽짜리 편지로 수 백만 달러 짜리 수리계약을 체결해 가면서 긴급수리에 나서 첫 주에 1대, 둘째 주에 9대, 월말에 제7폭격비행단이 작전에 복귀하고 10월 첫째 주까지 51대가 복귀했다고 하네요. 1953년 5월 11일 마지막 기체가 수리 완료됐습니다.

The story of the Tornado that hit Carswell AFB and damaged two-thirds of SAC’s B-36 Peacemaker Force

Having 2/3 of the B-36 Peacemaker force knocked out in less than 30 minutes taught SAC a lesson. Each time severe weather threatened Carswell AFB, as many B-36s as possible were flown out to other bases and would return the next day.

The B-36 was first conceived in 1941 as a transatlantic bomber to strike Europe from bases in the United States. By 1943, the focus switched from the European Theater to the Pacific for use against the Japanese home islands. After more design changes and greater success of the B-29s, the prototype XB-36s first flight was delayed until Aug. 8, 1946; nearly six years after initial design contracts were signed.

The B-36 Peacemaker is the largest production bomber ever built. Pilots referred to it as the “Magnesium Monster”.

The first operational B-36 was delivered to the Strategic Air Command in June 1948.

As told by by Dennis R. Jenkins and Don Pyeatt in their book Cold War Peacemaker: The Story of Cowtown and the Convair B-36, on Labor Day, Sep. 1, 1952 many of the base personnel and flight crews had the long weekend off. Weather forecasters had predicted severe thunderstorms for North Central Texas that afternoon with estimated winds of 60mph. As few personnel were on duty, few precautions were taken other than securing the B-36 aircraft with 3/8 inch steel cables. At 6:42pm, a tornado touched down on the base perimeter and struck the B-36 flightline directly. Maintenance docks used to work on the large bombers outdoors were thrown about and the steel cables tying down the bombers snapped as the planes were thrown about by the tornado like toys. Ruptured fuel tanks spilled thousands of gallons of high octane avgas all over the ramps. The anemometer on the Carswell control tower registered sustained winds over 90mph before being torn away by the storm. As the storm subsided, operations had to be transferred to nearby Meacham Field and other bases in the Southwest.

Two-thirds of the entire B-36 Peacemaker force was either damaged or destroyed in the tornado. One aircraft was completely shattered and would have to be written off while 72 bombers on the flightline and adjoining aprons were damaged and unflyable. Fortunately there were no fatalities given the long holiday weekend. Another 10 B-36s parked at the Convair plant were also damaged. Some of the bombers were shoved on top of each other and many had lost wings, empennages, or large fuselage sections. Because of the national priority placed on the B-36 fleet, by 5:30 the next morning a repair plan was underway with 1/3 of the repairs to be carried out by SAC, 1/3 of the repair work to be done by repair teams dispatched from Kelly AFB in San Antonio (the site of one of the USAF’s heavy logistics centers), and remaining 1/3 would be carried out by Convair. So urgent was the matter than a 1-page typed letter was the basis of a multi-million dollar contract for Convair for its share of the repair work. Project FIXIT returned one bomber to operational service the first week, and nine more B-36s in the second week after the tornado. In less than a month, the 7th Bomb Wing was back at full operational strength. Only one B-36 had to be written off out of the 83 damaged. By the end of the month, the round-the-clock effort had the 11th Bomb Wing operational and by the first week of October, 51 more aircraft were returned to service. The last repaired B-36 returned to duty on May 11, 1953.

Having 2/3 of the B-36 force knocked out in less than 30 minutes taught SAC a lesson. Each time severe weather threatened Carswell AFB, as many B-36s as possible were flown out to other bases and would return the next day.

Senator Lyndon B. Johnson of Texas and his Military Preparedness Committee conducted an investigation that concluded the base commanders had taken all the adequate measures proscribed at the time with an approaching storm. The investigations called for improved weather forecasting and an increase in the research of tornadic thunderstorms which over the years would not only benefit the USAF, but the general public as well.
