I work on a couple of Gooney Birds here in CA. The two I work on have cup holders but the standard size styrofoam cup wont fit in them. I have packed a cup or to up there while working on them and its hard to find a spot to set the cup when the tail is on the ground. I think the Military had some sort of small size back then. Maybe when the pilot is finished that is the only place to install it until the next stop?? Just my thoughts.

They sure are great airplanes and I enjoy wrenching on them.

Lots of luck holding a fuel sample in a foam cup hah

Cup holders are where you find them.

Styrophome + Gasoline + time = Napalm......Could get interesting

at JC i use a styrofoam cup to transfer a bit of Av gas to start my White Man's fire for the evening. Works real gud... "White mans fire, heat both sides of canyon"... Ugh
