I was standing on the back deck, with a beautiful, mostly sunny day.
Something caught my eye, coming from the South, moving very fast.
By my calculations, it traveled from directly over my house, to East of Victoria, B.C., in 2 seconds.
Made a 90° turn and headed towards Whidbey Island.
There seemed to be a shimmer around what looked like, a wing shape, with no fuselage visible.
The leading edge of the wing appeared dark., it looked like a flying wing.
And jet engine noise.
The estimated distance traveled in 2 seconds was 50 miles.
