Several pilots made out with 10mn+ in retirement money for their wives by fililng for divorce, collecting the money, only to remarry later.
Doobie or someone more qualified than I can chime in on the specifics of how the retirement benefits work.
Most surprising thing is that one of the pilots caught was rehired after promising to pay back the money. Also interesting it is not a fraud/criminal case, presumably because the language was not clear.
