neat... sounds pretty challenging....................................Look really nice,...................................Sounds great. Thanks !

You are not at orbital velocity, but you are probably going fast enough to induce quite a lot of drag at a reentry angles, say.. "Yeeees Ship have not at orbital velocity, but enough to burn in atmosphere. For direct ballistic trajectory (180°) velocity =~7 km/s and reentry angle more then 4-5°. "Extractor" stability burn in atmosphere.Using hover engines for dec velocity mean no fuel to evacuate people from crash site.I'm use other way. Starts from CC and heading 0°. On north pole turn plane to 115° (crash zone 64°-66°, center=65°. 180-65=115°). Activate IMFD and enter coordinates for center of crash zone (-65, -71). Wait for radius-vector of ship placed opposite target. Retrograde and down Per for 70 km.After reentry, make atmospheric landing and use LRA for locate "Iguana". Calculate new coordinates (using internal DGIII calculator ), enter new ccodinates into IMFD and make final aproach with low altitude ballistic "jump".

You can do this with about 40% of original fuel. You reenter about 10degrees south latitude and skim the atmosphere until about 40 degrees south where you start your rentry descent. I just used the Surface MFD to track position.
After landing, I use the LRA to find Iguana, which is usually within 200km.
Then I take off on new heading and keep speed about 300 m/sec and estimate distance by time. I purposely land short so that the Iguana is always roughly ahead of me. If it's less than 10km away, you can just just travel on the ground (not very realistic) at 50km or so -10km will take only about 3 minutes at 50km/sec.
Really enjoyed it.

Default Orbiter scenario for Shuttle-A...
