5:30 pm Friday, sounds like gunshots near Easterwood? Can't be the cannons to scare the starlings out of the trees on campus . . . too early in the day.

Don't know. Could be a Corps FTX.

I'll take "how do they start those big B-17 engines" for $200.

P-51 strafing run?

B17 backfiring?

The Coffman device used a large blank cartridge containing Cordite that, when fired, pushed a piston forward. A screw thread driven by the piston engaged with the engine, turning it over.[url=http://en.wikipedia.org/wiki/Coffman_engine_starter#cite_note-2][2][/url] This was in contrast with other type of cartridge starter which acted directly to drive the engine piston down and so turn the rest of the engine over, such as those used on the Field-Marshall agricultural diesel tractor.

I have no idea if they are using these. I just thought I would throw this out there because I am familiar with the explosive style starter.

Could have been the Special Forces exercises that are ongoing.

Interesting, thx for sharing Yuccadoo

I think the Special Forces are training here this summer.

Could just be folk down in the White Creek bottoms sighting in for turkey season.
