If you want to see the inside of a really big business jet–one that’s the size of an airliner–at the NBAA 2013 static display at Henderson Executive Airport, you may encounter a silk rope draped across the handrails at the bottom of the passenger stairs. A professionally attired man or woman standing by the rope will explain that the aircraft is being shown and then politely suggest, “Please come back later.” Later could take a long time.
