Thanks for the post. If they fly at 1500 feet as they’re said to have in NYC, they should be very visible - and audible.
It was funny; either on Thursday 4/30 or Friday 5/1 I heard multiple fighter jets flying by too fast to be landing at DTW. I ran out of the garage but they escaped my eyesight because of their speed, then maybe 5 minutes later another flight of two F-16's (I think) flew past same direction and speed flying southwest. About 2000 feet and at least 200 knots.
Here within 5 or 6 miles of Detroit Metro Airport fighter jets are a very rare sight or sound.
