So how does a big 757 make a smaller crater then a small Learjet?
So how could the soft ground at shanksville be soft enough to completely burry a plane while at the same time hard enough to transfer the impact energy to the seismic equipment. But...The Pentagon ground is hard enough to hold up an entire building but not hard enough to transfer seismic energy?

Photos? Interesting to say the least. The Lear Jet was also a glider at impact, whereas the 757 was deliberately crashed with power.
Seismic recordings at ARCESS from the second, larger explosion. The three components correspond to the three directions of ground motion. Although the explosion was a impulsive event the seismograms are complex due to the propagation of the seismic waves through the earth. The first arriving seismic phase is Pn followed by Pg.
TRANSLATION for non-seismologists: This figure shows three seismograms which are recording the ground shaking from the larger of the explosions. The ground moves in three dimensions, hence three components. The vertical component is up-down; the radial is horizontal shaking along a direction between the explosion source and the recording station; the transverse component shows horizontal shaking which is perpendicular to the radial direction. The shaking is complex due to the waves traveling through the Earth, although the ratio of the vertical to transverse shaking tells us that it was an explosion not an earthquake.
Regarding soft soil at the Pentagon and in Shanksville :
Imagen, dropping a stone near a seismograph from several meters high.
First on the concrete floor, secondly on a thick, WET sponge on that floor.
Try to visualize how the seismograph will record each event.
Btw, ever read about high-speed water skiing, and that the water act as concrete in case of a crash of the skier?
How would soft, muddy, wet soil from a former strip-mine react on a very-high-speed perpendicular impact of a passenger airliner? And transfer that impact energy to the underlaying bedrock, and subsequently to the seismographs?
Try to make an educated guess.
Mirageofdeceit : A couple of questions regarding seismic records:
1* Do you get different signatures for the same event if it occurs in different materials (allowing for the differences in transmission of those materials)?
2* For a given release of energy, is it reasonable to presume similar strength recordings at a given distance?
3* Is it possible for sites to be in a geological shadow, and not necessarily due to the relative positions of the occurrence and the recording?
4* Is anyone here able to verify the findings of the LDEO, and that the seismic records do indeed show the signature of an aircraft impact, rather than that of an explosion caused by HE for example? I'm unsure how likely LDEO are to ... not tell the truth ... or for the report to be tampered with.
I saw her expression of total terror on her face when recalling that event, and she broke out in tears, probably still realizing that the presence of such a low flying small plane (UAV) at the crash site has very grave implications.
It strongly suggests military deception on its way at that moment.
The white graph is in hundreds of a second timescale, the yellow ones in seconds. That's a factor 100 difference.

As you can see in these pictures, flight 93 did not crash in Shanksville even as they dug 15 plus feet down, no parts were found.

You show three photos that 'prove' that nothing crashed in Shanksville, PA, on 11 Sep 2001.
Please, indulge me, and explain exactly how those three pictures 'prove' any of your assertions.
