Thanks Will,
It's doubtful that any of the crew will survive the crash, but the resulting
fire hazard might need fire supression. The crash site will probably be in a
remote area -- not likely to be near an airport.
I've thought about just saying to heck with it and driving the doomed
helicopter into the ground and letting what happens happens.
Perhaps someone can comment on typical ways helicopters crash. From
movies I've seen usually it's in a spiral turning motion with a bottom
or slightly angled side/bottom impact.
The destruction will be great. I'm hoping the force will tear some
of the SEALs or crew in half. A decapation would be nice to see.
My experience as a young child is that most of the time pieces don't
break, and minifigs just get thrown several feet from the wreckage.
A belly landing will probably cause the least amount of damage with
the fuselage breaking into probably 3-4 chunks. With the SEAL team
in the open cargo bay -- they will probably just get chucked to their
death.
I've pondered the idea of crashing the model outside on a cement
patio. This would create a much more realistic crash than say
a carpet crash site. The impacting pieces would most likely
suffer scratching and I venture to guess several plate pieces would
snap against the unforgiving forces of cememt.
The crash will be more than just destroyed lego pieces and dead
minifigs. I'll be able to see what parts of the ship are weaker
than others. This experience will prove to provide data usefull
in creating a safer UH-60 in the future. The lifes of future
minifig SEALs and pilots depends on the sacrafices of these men.
To them it will be another training flight. They be put through
the paces quickly when they realize their flight controls have
been sabatoged, and coupled with engine failure. They will be
a steel bucket in the air with gravity as the ends to their means.
