At first I thought you were asking about birds. The aircraft was probably just passing through. We had one fly over our town; at first it looked like some old War War II airplane, but then it got closer and it was an Osprey. Probably going to the airport for fuel. Fighter jets from the Air National Guard do the same occasionally.
My wife saw one earlier in the afternoon. Could be the same one, or it could be two on similar paths.
I guess a fuel stop is a possibility.
I looked it up on adsb but either it’s not squawking or it’s down and the transponder’s off.
How long do these take to fuel up? I may monitor ADSB and see if it shows up on the way out.
Selfridge ANG here in S.E. Michigan has a fleet of them.....
I thought they were talking about the bird too.
