Give me some "holy sh... did that just happen" ideas

[Feathered_IV]

Unusual but distinctly BoB AI behavior, such as a group of Me110's that adopt a defensive ring when attacked.

Blenheim formations that bunch together and drop down to wavetop height when engaged.

Crew members that can be seen to be struggling to escape or even stuck in the hatch of doomed aircraft.

Parachutes that don't open.

Friendly fire. Both on the ground and in the air.

Aircraft that will abort from a formation.

Radios or even oxygen that can be knocked out.

Bombers with one wheel dangling as the hydraulics are shot away

Very rare - Bombers that drop their wheels in surrender and can be guided back to your base.
