The film you recall was of an F-100 being chased by an F-105 at Eglin. Flying a "rail cut" mission? Reason I ask is the copy I used to have of that tape mentioned it. The frag was immediate - both aircraft began burning within a second or two of the detonation. Great old film. v/r Gordon ====(A+C==== USN SAR Its always better to lose -an- engine, not -the- engine. |

If you ever wondered what those airplanes covered with the black/white
quadrant circles (like a BMW trademark) carrying stores with the same kind of markings were doing, it's so films can be shot with exact reference points to track the movement of the stores as they drop. I seem to recall this is why the pylons on the E/F Super hornet had to be angled out- -- Jim Atkins Twentynine Palms, CA USA Outside of a dog, a book is man's best friend.

Hi Paul.
Some of the others mentioned by people here sound pretty good, but as you said it floated back up and hit the tailplane, not exploded, it sounds very much like film of a trial drop of stores by an F-111, although from memory, I think it may have been a drop tank rather than a bomb. I'm pretty sure I have a copy here, and failing that, should have one at work. How soon did you need it? At the moment I can't convert it to a file to e-mail, but hopefully i'll have my camera back in the next few weeks and be able to convert it to digital.

Brooks Early prototypes of the F-105 attempted conventional rigging of the B-28-RE in the internal bomb-bay. No one anticipated the boundary layer along the fuselage at 600 knots IAS. When the bombbay opened for bomb release, shackles opened and bomb dropped a few inches but didn't come through the high speed airflow. Bombbay doors reclosed with bomb simply resting on the doors. (Shape--of course, not hot weapon!) Solution was a "displacing gear"--a roughly six-inch diameter, pneumatic piston that had about a two foot throw. Charged to a couple of thousand pounds/sq-inch, the piston was said to either push the bomb down or the airplane up. All became moot because the airplane never carried an internal nuke operationally. Displacing gear was still in place, however. Ed Rasimus Fighter Pilot (USAF-Ret) "When Thunder Rolled" Smithsonian Institution Press ISBN #1-58834-103-8 |

Quite a few airplanes did - the A-26/B-26 required that a spoiler be added ahead of teh bomb bay to assure a clean drop. The B-47 had a difficult time getting cleared to drop the Mk 5 nuclear bomb. The Mk 5 was the first "Lightweight" (For certain values of "light") nuclear bombs, and if didn't have the sectional density to cleanly break through the boundary layer around the B-47's bomb bay. The difficulty in getting things to fall out of a normal bomb bay was one of the drivers behind Martin's development of the rotating load-carrying bomb bay door for the XB-51, which they carried over to the B-57. -- Pete Stickney A strong conviction that something must be done is the parent of many bad measures. -- Daniel Webster |

ISTR an F-111 film of that, too. The store (or tank) separated, floated in the slipstream for a second or two, then went straight back and cleaned off the right stab. Pete |

Higher speeds mean the store can generate lift (just like any curved surface.) There were instances of jettisoned fuel tanks from F-105s climbing as much as 3000 feet above the release aircraft. I always wondered about the stories of separation tests on the A3J Vigilante with its rear ejection tunnel. Supposedly some of the weapon shapes could coast along in the wake for quite a distance. Nothing like a live nuke that follows you home.
