WHEN DRONES FALL FROM THE SKY:

The documents obtained by The Post detail scores of previously unreported crashes involving remotely controlled aircraft, challenging the federal government’s assurances that drones will be able to fly safely over populated areas and in the same airspace as passenger planes.

Military drones have slammed into homes, farms, runways, highways, waterways and, in one case, an Air Force C-130 Hercules transport plane in midair. No one has died in a drone accident, but the documents show that many catastrophes have been narrowly averted, often by a few feet, or a few seconds, or pure luck.

Luck doesn’t last forever.
