Nice little peek at the ultimate machine. Not counting the brains that made it, that is.

Quick trawl of t'internet....
Singles squash court is 9.75m x 5.64m x 6.4m = 352 cubic metres.
Air apparently weighs roughly 1.2 Kg/cubic metre so.....422 Kg.

I would say that the answer to the (rhetorical?) question in your header is yes. Not that there was any doubt about it because Rolls Royce had said it was!
Density of air at 15 degrees Celsius and ISA is 1.225kg/cubic metre. 1.3 tonnes is 1300kg. Volume of this mass of air is therefore 1300kg/1.225 kg/cubic metre or approx 1061 cubic metres. This would be the volume contained in a cube with sides approx 10.2 metres. This is in the same order of size as a squash court, I would think, although I never played the game.
Very enjoyable clip, by the way.
Just noticed that I was beaten to the post by someone who knows more about squash courts than I do.
