Those guys have drank too much coffee!
When I was a kid, a B-17 and B-24 landed at Bowman Field in Louisville, KY. I went inside both of them. It was getting late when I went inside the B-17. The pilot and co-pilot started going through the pre-flight check to start up. I thought "Do they even know I'm in here?". I slightly sped up my-self guided tour and exited the aircraft.
