There are thousands of solid UFO sightings every year—with just a handful of crashes in the past one hundred years.
I would say that is a solid engineering track record.
“There are thousands of solid UFO sightings every year—”
None of which are space aliens.
I am partial to the UFO crash in Aurora, Texas in 1897.
Took almost one hundred years for anyone to attempt a semi serious investigation into the incident.
The grave marker for the “pilot” was removed 30-40 some odd years ago from the Aurora cemetery
