What has to be taken into the equation is when dropping ordinance from an aircraft. One of the laws of aerodynamics come into force.
You drop quite a few hundred pounds of weight, weight and lift are opposites. So, when you drop weight, lift takes over and aircraft tend to rise very quickly!! I have heard the term, 'jumped' when in relation to dropping a load!!
(In the tiny Wasp, when we dropped a torpedo or pair of depth charges we could feel the rise which the pilot then has to take immediate correctional inputs to the controls!!)
Additionally, there may be operational procedures pilots may be required to carry out. eg, bank hard over or climb rapidly. Not withstanding ducking and diving from incoming weapons!!
Another thought, images from astern of the dropping aircraft are going to be like dragons teeth!! Most aircraft astern will be in the same boat as the dropping aircraft, that is pilot concentrating on the target and not clutching a camera. That said, there may be rare images of a drop during perhaps a trial or test drop. I say rare because most developers of weapons would be owned by the companies.
I'll keep on scouring the net in the time being Andy!! I have only images of DC's being dropped.
