Best info I've seen thus far in this thread.
To be honest, my criticism of the formation photo has been entirely sarcastic thus far, as was pointed out by Hoser. Notice I used the phrase "ridiculous looking"? As has been pointed out, I don't know the first f*cking thing about airdrop TTPs, nor the reasons why things are done that way. Why would I? You guys are the experts on it, not me...so long as the iron gets on target (or DZ as the case may be) on time, who am I to care?
I was merely pointing out that the traditional convention for a formation is one in which the airplanes are close together in some geometric relationship. To me, the photo looked like it depicted airplanes that, with the exception of one 2-ship echelon, and two 3-ship echelons, just happened to be in the same piece of sky at the same time.
That was funny ha-ha to me. Guess it wasn't to you humor-impaired guys out there. Not trying to sh*t in the airdrop bowl of wheaties in any way.
