The link is of a F4 jet being run into a concrete wall.  I would like
to see the rest of the test video...where this one leaves off.

Hello Carl,

The U.S. Sandia National Laboratories conducted and filmed the test in 1988.

?In 1988 Sandia National Laboratories in USA demonstrated the unequal
distribution of energy absorption that occurs when an aircraft impacts
a massive, hardened target. The test involved a rocket-propelled F4
Phantom jet (about 27 tonnes, with both engines close together in the
fuselage) hitting a 3.7m thick slab of concrete at 765 km/h. This was
to see whether a proposed Japanese nuclear power plant could withstand
the impact of a heavy aircraft. It showed how most of the collision
energy goes into the destruction of the aircraft itself - about 96% of
the aircraft's kinetic energy went into the its destruction and some
penetration of the concrete, while the remaining 4% was dissipated in
accelerating the 700-tonne slab. The maximum penetration of the
concrete in this experiment was 60 mm, but comparison with fixed
reactor containment needs to take account of the 4% of energy
transmitted to the slab.?

From Sandia National Laboratories website:

Footage of 1988 rocket-sled test.

?F4 test videostream ? 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. ?

Thank you Bobbie7!!!  This is great.  I was hoping to get footage from
the aftermath of the crash...after the dust much of the
plane and research tower remained.  PLEASE USE THIS NOTE FOR 100%

Dear Carl,

I'm delighted that you are pleased with the results of  my research.

If I locate additional footage I will let you know. 

Another option would be to get in touch with Sandia directly.
