The best heaidng for a bombrun was a zero druft heaidng sinve the Norden had
a
cumulative error (small) as the dirft angle increased. This was due to RCCTE
(Range Component of Cross Trail Error) because in a right triangle the
hypotenuse is always longer than either of the legs.

Pretty much true of any bomb run with any system. On the other hand there is
something to be said for diffusing the defenses and attacking from the least
heavily defended direction. Better to get to the target knowing there is a
cartain amount of inaccuracy in the bomb aiming device than to not get there at
all.
