You get more exercise out of a treadmill if it’s on an inclined plane. Thought you might like to know.
Plane? Treadmill? I’ll leave it alone 
Sorry - no snark was intended.
Then I certainly apologize.
The Goodyear Blimp based in Akron has a huge hangar at the Fulton local airport. We always used to drive by on the way to Strickland’s for frozen custard.

Okay, I didn’t think that one was going to take off…
Here’s a link to a view of the hanger in Pompano beach. When I flew the blimp they just had the mooring mast, the hanger was built later.
