re: #83 zombie

Found it. It was a C-5 Galaxy, coming straight in from over the Pacific, heading straight for Travis Air Force Base. Presumably coming from Guam. It was taking a flight path civilian planes NEVER take.

The setting sun caught it just right, illuminating the plane and the contrail perfectly.

They had those planes flying into Israel in ‘73, loaded with stuff. The C-5 makes a 747 look like a mosquito!
