During WW2, many German night fighters were fitted with a gun firing
upwards,
to attack bombers.

Actually: 1. It could be one or *multiple* guns
2. They were at an oblique angle
3. It came about when some genius in
the
Luftwaffe realized that RAF
bombers had *no* belly defenses;

Not strictly accurate , some Lancasters had ventral guns, the
problem was that the space was needed for the H2S radar
installation



[GEE! IF Churchill had asked NICELY; we
COULD
have sold
him some B-17/24 type BALL
TURRETS OR THE PLANS
FOR SAME! ]


Given that the RAF had a number of B-17's complete
with ball turrets I rather think the idea was not completely
unknown.
