I thought I had heard he called mayday, but have not read it in any of the account... or I missed it, which is likely. Was any other verbage provided by the Pilot at the mayday call?
I don’t know anymore about the mayday call. That picture you posted was one I hadn’t seen. His head is forward, but I’m not sure why that should be if he was in a harness. Unless he undid the harness.
