Hopefully they have been more thorough than the designers of the twin
towers that were also supposed to withstand an airliner IIRC. The heat
of the fuel fire weakened the steelwork leading to their collapse
despite withstanding the initial impact as designed. A similar
problem may occur with Nuclear reactors.

Twin towers were designed to *easily* take the impact of a loaded 707 - the
most widely used airliner at the time they were built.
