For those that want to down load the video or pictures the 1988 test of a
F-4 crash into reinforced concrete, go to the Sandia National Laboratories

   The purpose of the test was to determine the impact force, versus time,
due to the impact, of a complete F-4 Phantom - including both engines - onto
a massive, essentially rigid reinforced concrete target (3.66 meters thick).
Previous tests used F-4 engines at similar speeds. The test was not intended
to demonstrate the performance (survivability) of any particular type of
concrete structure to aircraft impact. The impact occurred at the nominal
velocity of 215 meters per second (about 480 mph). The mass of the jet fuel
was simulated by water; the effects of fire following such a collision was
not a part of the test. The test established that the major impact force was
from the engines. The test was performed by Sandia National Laboratories
under terms of a contract with the Muto Institute of Structural Mechanics,
Inc., of Tokyo.

In our presentation to the Quebec parliamentary commission on energy last
Tuesday, we included a couple of relevant slides with graphics illustrating
some of the issues discussed in this thread -- they are near the end, on
