Medical Expired???
Ok...now I know that many of you would not do this but in Bangkok you can have anything in the world forged including airmen medicals and the Thai DCA does not confirm the validity of any pilot documentation from Foriegn Pilots, including Indonesions, with the issuing authority, FAA, CAA or JAA.
There were rumors of an Orient Thai charter flight into Cambodia back in 2005 that landed and was "ramp checked" by the Cambodian Aviation Authority. There were 4 pilots on board and only one was legal to fly with current documentation. The Chief Pilot of the 757 fleet at that time was on board and guess what? He was one of those who did not have current documents.
So please do not say it was not possible for someone to fly with a medical pulled.
