[net.aviation] lift

A small point, but isn't the "action-reaction" lift referred to
known as planar lift? Seems to me I've read figures as high as 30% for
planar lift.

Question: does planar lift account for the low speed effectiveness of 
fuselage strakes placed near the intakes of high performance a/c?
I refer to types like the F-16, F-20, and SR-71 in particular.

Is planar lift a significant factor in delta winged aircraft? The most
extreme exaple I can think of here is the homebuilt Dyke Delta, which
has a lot of wing area for its size.
