Can you think of a better way to create a wing shaped gash with a hole in it in a very short time?
If you think C4, have at it.
I can think of several better ways. C4 for the center crater, and layers of det cord to make the wing impressions. Probably could be set up in an hour or two. Or bring in a back hoe and dig it that way. Or since the crash site location wasn't critical, just get an actual 757 and have the pilot parachute out and let the plane hit wherever.
