Well, here are the top 5 answers I gave today:
About 30,000 feet
About 250 miles
Usually about 29 people
I sit in one of these seats
Yeah, its a bit warm (in the flight suit), but it could be worse
I stood outside at the entry/exit stairs and answered a few questions, mostly involving the heat (we had someone collapse shortly after they entered the jet, that was fun) but spent at least that much time inside, where the AC was on answering a lot more questions and explaining who sits where and what they do.
All in all it was a pretty good time. Its fun showing people what goes on in the E-3, and I'd probably sign up to do this again someday...especially if it was a TDY to a nice location
Only one person stumped me today, and that was a question about if our radios were upgraded to some kind of equipment standard. I found out the answer later on, so next year I'll be ready.
