(from an amateur observer) Watching the last of the landing videos that were linked, the belly warning lamp goes out about five seconds before touch down. Obviously, it might NOT have been but the questions are:
- Once commited to the belly landing, would SOP be to shut down the engines?
- and ALL possible electrical circuits?
- Would it be done Prior to or at touchdown?
- If such circuits are isolated - would that leave the handling pilot with no control surface?
- In which case, a prescribed list of circuits to be isolated to reduce fire risk?
