was clear cut in that way. there were two helicopters going into the compound. one of them failed but we re sold there was a third helicopter that assisted in getting the military personnel and bin laden s body out of there. that was smart to have a backup. they may have had more than one backup helicopter? absolutely, wolf. we learned a lot from desert one which was a failed iranian hostage mission and we learned a lot from roberts ridge, which was some problems that we had earlier on which was after tora bora. we always want to have helicopters in reserve and not knowing the exact details, but i can tell you we probably had a couple operation points outside the perimeter of the compound.
