The A3D was not the only member of that family that experienced such a

it
was unnerving to do a bomb drop from the Destroyer because it sometimes
had
a habit of having bombs "bounce" around in the bomb bay after release
before
actually leaving the aircraft (which may explain why its career as a
bomber
was rather short).

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.

The boundary layer flow was the reason for the B-66 problem as well, from
what I remember of the gent's explanation. But in his case ISTR he
experienced it when dropping conventional ordnance during a training
evolution; I remember him distinctly mentioning "bombs" (plural) thudding
around, and IIRC he indicated a little pull up on the nose was used to
ensure their eventual departure. I do know he said it was not a pleasant
experience!
