Since the floating structure is designed
to have enough strength to the crash of the aircraft, the damage
is very small in case of the crash of the aircraft horizontal condition
and even in case of vertical condition it is limited to@the local
area at the surface of the floating structure not to cause further
damage. The example of the investigation on an aircraft crash is as follows:
Aircraft ---- B747
Weight ---- 500 tons
Velocity ---- 100 m / s (360km/h)
Direction ---- Vertical
<Result> ---- Limited local damage on the surface
