Destined for Philippine Air Lines. It's interesting to speculate why it has the customer registration on it before painting in PAL livery. If it was for test flying it could have worn a B-Class registration instead. Perhaps the original intention was to deliver it unpainted since there was a clandestine CIA connection to the story of the PAL fleet.
