True, but you'd need, at minimum, a well-trained crew to operate. The catapult settings vary by take-off weight. Who manages that? Does each airline run their own crew (contract) as they do other ground services? Or does the airport run it?

The airframes would have be heavier, beefed up to take that load. FWIW, the Navy version of the F-35 weighs ~5000lbs more than the AF version's 29000 dry weight (granted, that's also additional folding wing changes). It also costs about 20% more per unit.

Anyways, it's all certainly possible. Just impractical without a real need.

But catapult launch ballistic passenger gliders would be pretty cool.
