Mexican news is reporting the lost aircraft as N7560Q 421B-0346.
There are mixed reports whether the aircraft has been found or not?, AP reported the crash found near El Bravo Mexico, but then retracted the story.
Yeah I saw this one too, but I don’t think it’s the plane. It departed KELP at 0837 local, and went to Alpine. The 421 in question was supposed to check out some reservoir over Mexico, then to Presidio (T77), which is right on the border. VFR and/or blocked perhaps?
Chances are that if it was a flight to go view something that it was VFR.
