Higher speeds mean the store can generate lift (just like any

IIRC, "curved" is unnecessary here. After all, they do say that,
given enough thrust, a brick will fly, do they not?

Actually, no. Lift is balanced by weight, while thrust opposes drag.
The brick (AKA F-4) would not really "fly", but simply be propelled in
the desired direction. It is the tendency for airflow to accelerate
over a curved surface creating a low pressure area that causes "lift".
The dropped store had better be curved if you want to get lift, since
it isn't supplied with thrust.

....except when you're looking at something like the B-70 "waverider"
technique, where the underside of the plane provides compression lift,
without providing classical Bernoulli-type lift.
