Believe it or not, aircraft don't need Navigators anymore. You see as well as the thrust and Lift Demons used by all Lockheed aircraft in this particular case they have installed lots of nav pixies who do lots and lots of calculations really really quickly. The best thing is, is that they are always right.
You're trolling... Right? Reports state that the drop took place maybe as much as, (not believing it word for word), a mile and a half away... It's ok to be lost... We've all been there. But to throw 30 or more chaps out of the back of a kite on a hunch is a bit much. Having spent more time than I care to remember on Otterburn TA I can, with reasonable certainty, say that 3/4 of a mile off track will most likely put the parachutists somewhere they'd rather not be. The crew messed up. It's actually commendable to admit it and fix the system so we don't kill troops in the future...
