Tamecat I'm sure its possible to land on the same deck you cat lanuch from but the odds of it are like that mountain top your speaking of just a lot smaller. You would have to reinforce your airframe a lot more to keep from ripping the rear of your plane off when you grab an arresting wire. Some of the load could be transfered to a shock cord, but i don't think it would be worth risking a 6000.00 aircraft on to attempt it, odds aren't good at hitting a 4'x32' wide deck every-time. This could be done safely with a slower prop plane I'm sure but not a fast moving heavy jet.
The Cat launch i have planned would be made from 4 sheets of ply (32')with the shuttle built to it and hinged so all 4 sheets would fold and would have small wheels and a handle to make it easy to transport, just roll it in or out of the trailer, unfold it and you ready to launch. I would set it up alone side the runway for launching when it would be out of the way and land normally on the runway.
