A while ago, I saw video footage of a bomb being released from a
fighter-bomber under test conditions. It was on an aviation
documentary. The high speed camera then shows it climb up and destroy
the tailplane. I don't think they quite got their trajectory calcs
right!

Modern aircraft employ "ejector" carts which propel the store away
from the rack using a small pyrotechnic charge and a "foot" or pusher.
Earlier aircraft simply used suspension hooks that opened to release
the weapon allowing it to fall away.

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.

Instability caused by a bent fin can also cause a pitch up moment on
release.

I have also seen something. A Fantom (?) or the like and two chase planes.
Debris or the bomb (missile?) also hits one of the chase planes and it is
destroyed. This was part of a series of accident studies including an F-16
landing with a wheel missing or locked up main gear. The guy ejects after the
F-16 safely comes to a stop, perhaps fearing a collapse and fire.

The film you recall was of an F-100 being chased by an F-105 at Eglin.
They were dropping early versions of the MLU-10B land mine. The mine
broached on impact with the ground from a 100' lay-down delivery and
rose up to hit the chasing aircraft. The weapon was inert, but the
impact still destroyed the chase and the pilot ejected.
