Since only VC10Ks were based in the Malvinas, the freight door question was somewhat irrelevant.
Unless things have changed and the VC10 now has an updated DF system (which I very much doubt..), locating a 121.5 or 406 MHz PLB will be impossible.
No maritime VHF either.
But if someone has a position for a 406 Mhz PLB and the HFs actually work so that the position can be transmitted to the crew, it's vaguely possible that the aircraft could be sent to the approximate area. But what it would do when it arrived on scene, I cannot imagine.....
