I don't think anyone who knows anything at all about aviation would believe he landed-on all by himself. (After all, he's never done any naval flying, hasn't flown the S3B before, and I don't believe he's current on anything) The story that he didn't arrive in a F14 or F18 "for security reasons" is propaganda.
Why, d'you reckon, didn't he rock up in a chopper or a COD? Possibly because he wouldn't have had the opportunity of being photographed in full Top Gun flying rig? Utter political theatre. Apparently the whole exercise cost $1 million!
