    I knew I had seen some pics of a BUFF that had gone tail-less at one point. This came across my desk today and it got me thinking of the effects of losing the tail and the results that it has had in some more recent times. But the failure in this case wasn't the whole tail, although most if it was gone, there was some left to keep the airplane pointed in the right direction, and that was enough... Unfortunatley the Airbus tail appears to break off so cleanly that there isn't a stub left to keep things straight. How many people lost their life on this lesson?



    January 10, 1964, started out as a typical day for the flight test group at Boeing's Wichita plant. Pilot Chuck Fisher took off in a B-52H with a three-man Boeing crew, flying a low-level profile to obtain structural data.

    Over Colorado, cruising 500 feet above the mountainous terrain, the B-52 encountered some turbulence. Fisher climbed to 14,300 feet looking for smoother air. At this point the typical day ended. The bomber flew into clear-air turbulence. It felt as if the plane had been placed in a giant high-speed elevator, shoved up and down, and hit by a heavy blow on its right side.

    Fisher told the crew to prepare to abandon the plane. He slowed the aircraft and dropped to about 5,000 feet to make it easier to bail out. Then Fisher regained some control. He climbed slowly to 16,000 feet to put some safety room between the plane and the ground. He informed Wichita about what was happening. Although control was difficult, Fisher said he believed he could get the plane back in one piece.

    Response to the situation at Wichita , and elsewhere, was immediate. An emergency control center was set up in the office of Wichita's director of flight test. Key Boeing engineers and other specialists were summoned to provide their expertise. Federal Aviation Administration air traffic control centers at Denver and Kansas City cleared the air around the troubled plane. A Strategic Air Command B-52 in the area maintained radio contact with the crew of the Wichita B-52.

    As Fisher got closer to Wichita, a Boeing chase plane flew up to meet him and to visually report the damage. When Dale Felix, flying an F-100 fighter, came alongside Fisher's B-52, he couldn't believe what he saw: The B-52's vertical tail was gone.

    Felix broke the news to Fisher and those gathered in the control center. There was no panic. Everyone on the plane and in the control center knew they could be called upon at any time for just such a situation. In the emergency control center, the engineers began making calculations and suggesting the best way to get the plane down safely. The Air Force was also lending assistance. A B-52, just taking off for a routine flight, was used to test the various flight configurations suggested by the specialists before Fisher had to try them.

    As high gusty winds rolled into Wichita, the decision was made to divert the B-52 to Blytheville Air Force Base in Northeastern Arkansas. Boeing specialists from the emergency control center took off in a KC-135 and accompanied Fisher to Blytheville, serving as an airborne control center.

    Six hours after the incident first occurred, Fisher and his crew brought in the damaged B-52 for a safe landing. "I'm very proud of this crew and this airplane," Fisher said. "Also we had a lot people helping us, and we're very thankful for that." The B-52, Fisher said, "Is the finest airplane I ever flew."

    Switches, you had to have been at Boeing at the time?

    Indeed I was at Boeing and working on the SST proposal in 1964. Directional control of the B-52 was achieved by differential outboard spoilers and thrust. I was told that it worked quite well and I have no doubt that the order to have control cable connections to stab trim and outboard spoilers on the 777 goes back to this incident. Also the total electrical power failure and loss of the computers on an Airbus helped to solidify the decision.

    This happened to more than one B-52. There was another that survived, and one on a training mission (a tall tail B-52C) that crashed in Maine after losing it's entire vertical a stab in a storm.

    A B-36 Peacemaker also recovered safely after completing a USAF Academy fly by no less (they were probably scared LeMay would give 'em sheet if they aborted) after losing it's entire rudder asembly and a small part of the vertical stab. Can't find a pic online, but have one in my SAC history book at home. I'll scan it later today and post it here.

    All those engines way out there on those long wings are plenty good to steer that beast. Rudder or not.
