A solar-powered Airbus Zephyr has drawn a hand with its flight path in the sky over the Yuma Proving Ground.
In accordance with Flightradar24 data, Zephyr UAV turned on its transponder over the Mexican Gulf at approximately 13:12 UTC, July 1.
We assume that it was the last part of the many-day flight from the Yuma Proving Ground to Belize and back to the Yuma Proving Ground, which started on June 20.
This flight has some tracking issues on Flightradar24, but we almost have no doubts that it is the same flight.
If our assumptions are correct, the total time of this flight may be not less than 400 hours at the moment this article was written.
