Plane interference

I was wearing a Garmin 235- I live near a golf course and an airport. I was waiting on GPS signal to my watch which finally kicked in, I ran 2/10 of a mile when a military plane flew over me Although I couldn’t see it ,I could hear it’s loud roar. I checked my watch to locate pace distance etc. my watch immediately changed from the two tents and started rolling over and went up in a hurry to 3.04  miles, then the watch started counting down to 2.04 miles and stayed there the rest of my run. It continued to give me elapsed time but my pace was well below I normally run, so I thought my watch was messing up. When I looked at my stats at the end of the run, with the map of my course, The map showed I went east through the golf course through the airport turned around came back down headed west which was not my route at all. I know the mileage I ran , and my watch metrics were off. Is it possible that somehow GPS with the plane and my watch picked each other up. Has anybody else experienced something such as this? All I can brag about is that I ran 143.5 mph that day.

    Unless it was an electronic warfare aircraft with all its jamming equipment enabled, it is highly unlikely that a passing airplane would cause any issues with your GPS receiver. I'd rather suspect some airport equipment (radars, ILS and so on), but frankly, this is not very probable either. You can confirm this by checking if this happens again in the same area (and does not happen elsewhere).

    Actually the Air Force Base to the west of me 10 miles away is the Strategic Command Air Combat 7 th Bomb wing home of the B1 Lancer, C-130, T-38 and now the B-21. These planes are quiet capable of all the GPS jamming . It was a military plane that flew over  me . I’ve lived here for 40 years I know the difference between a military plane and a puddle jumper at the local airport.  My guess is since I run near the local airport all of the time I’ve never experienced this, but it was at the right time at one of the military planes flew over me that I think this happened. Just wondering if his airplane recorded a nine minute mile LOL

    Nah, that's not how it works. The GPS receiver in your watch receives signals from satellites, and does not transmit anything, so your watch could not have interfered with the aircraft's avionics in any way. The other way around would be possible in theory if the aircraft employed some sort of GPS spoofing and/or jamming.

    I surely don’t have any knowledge of how all this works, Thanks for the explanation.
