Don't want to come to wrong conclusion but that poor co-pilot is still under a train!
I would like to see your face when your left/right seat collapse and you aren't capable of doing nothing (also if you are the best CPRest in the world)!
Performing a pilot incapacitation landing can be a piece of cake (especially because trained in the sim), compare to timely handle such a psychological strong event like seen someone dying close to you!
