Parachute aircraft landing on your head
Leaving out how unlikely it is to actually land on you personally, or your property, assuming it is blaring some sort of warning siren as it falls you'd have plenty of time to look up and get out of the way.
If it lands on your roof then I guess that's your bad luck, but people have cars crash into their houses all the time and sometimes die or are seriously injured in their own bed. That would be a lot less likely with this craft parachuting onto your roof, especially if you live where there's enough winter that roofs are engineered for snow load.
