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.
