Pilots are always on the radio so I assume he's radio'd the aiport and advised them what was going on and they would have worked out a plan of attack and taken it from there. I assume they would just put it on the back of a tow truck?
No need to have the airport on speed dial lol.
Every time we leave the boat ramp we register with sea rescue, give them an estimate of what we will be doing and what time we are due to be home. If something happens at sea then you call up sea rescue (many people forget about the whole mayday / pan pan thing so they just "talk" so to speak), advise them what the problem is and let them sort it out. If its been a good day with smiling fish gods, you call sea rescue back at the ramp, thank them for their coverage and let them know you are safe.
