Not sure about the fraud probe or any repayment to the pilots, but MH has definitely been trying to erase records of his adventures online. His Wikipedia screenname (Cryton4) appeared again this last Monday on the "history" section of his Wikipedia page - this time trying to delete the page. Unfortunately for him, Wikipedia leaves it up to other editors to see if there's valid reason for deletion. There's not....nothing beyond him wanting to pretend the whole thing never happened.
This appears at the bottom of his user page (written to him from another Wikipedia editor):
"Cryton4: your diligence in creating and nurturing the [MH] page was notable. But that does not mean it be so easily deleted. You used it very effectively to promote yourself and your airline. But that confers no right to then delete the page."
I would imagine MH has attempted to jump ship at this point since his gf is from the US, according to Wikipedia. I wonder where the money to do that would come from....hmmm....
