not necessarily. These guys weren’t exactly in the complete middle of nowhere. They were just west of the town of Eloy, AZ and just south of both Arizona City and Casa Grande, just west of an active airway and Interstate 10. This wasn’t exactly the Mojave desert or the Gila Bend bombing range. Some predications, but some glaring oversights also.
Not really the place for uncontrolled pilotless aircraft, tooling through the air with no ability to see and avoid anything. Had one of these planes recovered somehow and flew along by itself pilotless, to crash into some populated area, would be a big risk.
Their rationale for wanting exemptions? Because they’d already made media contacts and commitments. That’s their problem for doing that before securing exemptions. Not the FAAs problem.
Barnstormers of the 1920s were doing stuff that was largely a hazard to themselves if it went bad, not necessarily a hazard to other aircraft and persons on the ground. Hence the FAAs concern. I mean, go do this in the Mojave desert or in some other middle of nowhere area. But no, that wouldn’t be convenient for them.
