Your side of the argument sounds more reasonable to me...
I guess that's why he's teaching physics at a shipyard and not at MIT.
The bomb has the same velocity as the aircraft at the time of release
and then
will quicky slow down due to wind friction ( and probably by design
too). The concept is
more or less the same as an artillery shell trajectory. In the aircraft
case the "muzzle velocity" is much slower.
