J. set up a tent in the yard for Sukkot and I went out to catch the breeze and the moon. The tent roof is mesh (open to the sky is the requirement) and lying on my back I saw planes going back and forth.
My father had a longstanding research project around using phase cancellation to reduce noise from jet engines. That’s what I’d tell people who asked what he did: he works on making airplanes quieter. The air force base was on the other side of town but you still saw jets arcing in formation; the cumbrous A-10 Warthog was the only one I knew by sight. Military equipment was always on the test. You were expected to know (from where?) what an Uzi was.
