@Xenophobic: Rought kinetic energy of a 757 @ 530 mph: https://www.calculatorsoup.com/calculators/physics/kinetic.php?given_data=energy&KE_units=joule&m=60000&m_units=pound+%28avdp%29&v=530&v_units=mile+per+hour&sf=0&given_data_last=energy&action=solve 763,891,000 Joules = 563,417,087 foot lbs of energy. Check out the history of kinetic weapons.  Specifically "Lazy Dog missiles".  About the size of a AA battery and caused havoc.    " That’s the fundamental logic underpinning the U.S. Navy’s highly touted electromagnetic railgun, which can blast a 25-pound “hypervelocity projectile” with 32-megajoule muzzle energy through seven steel plates and obliterate whatever that armor is supposed to protect." 32 mega joule or 32,000,000 Joules.  25 lbs.  Very small hole.  Lots of other variables and blast effects.  Were talking ~15X the kinetic energy.
