Heaven's Stairway Incident

On May 14, 2021, a large mesoscale convective system (MCS) formed unexpectedly over the city of Columbus, Ohio, engulfing all the planes flying within roughly 200 kilometers of the system center.

As the aircraft involved mysteriously disappeared on air traffic control radar, it was colloquially known as the Heaven's Stairway Incident by aviation authorities.

Wreckage

Several flight recorders were found scattered around fields near Toledo.

A piece of metal, presumed to be a part of an aircraft's engine fan blade, was found near a farm. The farm owner reportedly took the blade as a souvenir.
