KSP - Space Shuttle RTLS abort with kOS

Space Shuttle Discovery performing a Return To Launch Site abort following an engine failure in Kerbal Space Program.
The Shuttle is under complete kOS control from liftoff to approach initiation.
I use my own ascent and reentry guidance scripts, modified to perform the abort.
