I've not seen any F35's yet. Also used to see the occaisional big US helicopter, I can never remember which designation (MH-53?), but they seem to have disappeared over the last few years, as have the KC-10's. There is a RC-135 (I think, or something like that) that is also now a regular.
Could it be the Super Stallion?
https://en.wikipedia.org/wiki/Sikorsky_CH-53E_Super_StallionI flew in the back of one once, many years ago.
The A-10 is indeed a beast of a plane and has a fascinating history. The yanks even consulted
https://en.wikipedia.org/wiki/Hans-Ulrich_Rudel on its design. The USAF never liked it but the US Congress won't let them give it up until they can prove a capability to give ground troops Close Air Support.
I dabble in the simulator that the guy in the OP is using for his cockpit. It's an amazing piece of software and a lot of fun if you're into aviation at all but I won't be building a cockpit myself. On the other hand, the N+1 fund could be diverted to some VR gear some day
The A-10C and the F-14B are both fully modelled and a lot of fun to "fly" and several more planes are available to learn.
