Very, very very different circumstances between PAA 103 and UAL 93!!!
Please read verfy carefully....
Pan Am Boeing 747 had a BOMB onboard, in a suitcase, in the forward cargo compartment. It EXPLODED while the airplane was at cruise altitude.
I shall repeat,and enhance: It exploded at its initial cruise altitude of 31,000 feet. Disintegrated. Up there.
At this point The Maid of the Seas was flying at 31,000 feet (9,400 m) on a heading of 316 degrees magnetic, and at a speed of 313
knots (580 km/h) calibrated airspeed, at 19:02:46.9.
Please click on this link, and pay particular attention to the description of how the airplane broke apart, mid-flight:
OK, done reading? Good. Now, when the pieces began to fall to the ground, they only accelerated only as fast as the force of gravity, they aren't
being propelled by the thrust of the engines.
I hate to seem ghoulish, but this lesson is important for understanding the differences.
As it descended, the fuselage broke into smaller pieces, with the section attached to the wings landing first (46.5 seconds after the
It hit in the Scottish village, among the buildings and pavement. The forward fuselage section, containing the cockpit, would have fell slower, and
impacted at a lower speed.
Compared to UAL 93, deliberately dove into the ground, and by chance impacted in fairly soft soil. IF UAL 93 had hit in different terrain, then we
wouldn't be having this discussion at all.
The fact that the momentum and forces caused the two recorders to penetrate so deeply should not be dismissed --- nor should the data recovered from
You may wish to look at another example of a "lawn dart" impact, although both at slower speeds than UAL 93 --- UAL 585 and USAir 427.
While neither is exactly the same, because of the ground diffrences, there are some similarities.
Also, Value Jet 592, which did a high-speed into a swamp. Knee-deep water, and of course wet soil (meaning soft) and there were NO pieces sticking up
out of the water. It disappeared.
PSA 1771....high-speed, but a rocky hillside. Didn't bury as much, but some did.
Finally, the only photos that keep popping up on the Internet are the same ones. You do NOT see a whole lot of others, like what the debris back in
the trees looked like.
Wally Miller should cough those up, he seemed to have a stack of 'em, in that one interview he taped.
