Captain overreacted to a cracked outer pane, panicked, stopped flying the jet, rushed things thereby insuring the copilot had no opportunity to be any assistance, lied to investigators and perhaps intentionally damaged the engine. Winner
All comm/nav data can be set directly or through the FMS in the G-4. It is quite easy to perform an immediate return for landing without ever touching the FMS. But this was not a situation that required an immediate return.
Outer panes can go quietly or with quite a loud bang. I bet this one let go with some noise and scared the captain out of the sky.
Best,
