I think he'd have a helicopter pick him up, and take him a couple of miles to be transferred to a supersonic jet.

That jet would take him 100 miles into the atlantic and he and an accomplice parachute out with a liferaft and little engine.

The plane carries on to mexico as a decoy.

Radars aren't good enough to see small craft far from the shore in the ocean, so he can stay at sea as long as he likes and land anywhere. The search area would be huge - if we can't find MH370, we can't find him!
