180 degree contrail

I think I left the stove on...

High-altitude holding pattern would be my guess.

This is not an unusual sight along the Oregon coast. Seems like some newer aircraft leave KPAE and fly down the coast , then pull a 180 turn and return to KPAE. Test and promo flights.

Aerial refueling and airborne radar/surveillance aircraft will fly large racetracks in the sky that sometimes will leave a contrail. Most of the time they try not to fly at altitudes that will leave a contrail.

If only there was a website that tracked aircraft by time and location......

I also dont rexall very often either. Um just a jet making a 180 for some reason oh who really cares.
