A Simple Proof that the Official Story of the Flight 93 Crash is Wrong

Officially flight 93 was crashed intentionally by the hijackers into the ground. According to Jere Longman, who wrote the definitive account of flight 93 in his book "Among the Heroes", when the plane crashed going 600 mph, it burrowed head-first into the ground. Officially, most of the plane's fuselage was found buried 25-40 feet underground. Even the two black boxes were found at 15 feet and 25 feet below the ground surface. However, the plane also exploded, showering large pieces of debris for hundreds of yards and very light debris, for miles. The explosion produced a huge noise that nearby residents heard and also produced a large mushroom cloud. The crash also apprently produced a seismic vibration, though the 9/11 commission doesn't believe this evidence as the time of the signal was 10:06am and not 10:03am when the commission says flight 93 crashed.

Here is what the crater of the flight 93 crash looked like.

Here is the problem: the flight data recorders and the cockpit voice recorders (the black boxes) are located in the tail of the plane.

If the plane went into the ground head first, and the black boxes went into the ground, this means the tail went into the ground as well.

This PROVES that flight 93 either:

1) went in the hole head-first and DID NOT explode (since the explosion would have shot out the rear of the plane, blowing off the tail)

or

2) didn't go into the hole and the crater is a hoax.

I submit that it is impossible that the plane's fuselage including the tail section could have burrowed deeply into the ground but at the same time exploded so violently as to shower human remains and aircraft debris all over above ground.
