""It took 11 years to find out how Boeing was able to ring a ground engineer in Jakarta who got to us after about 15 to 20 minutes after landing.""
The British Embassy in Jakarta were called at least 45 minutes before the flight landed by Halim Air Traffic saying the plane had lost all four - I met the embassy duty officer a few years later and he said the brown stuff was all over the place well before it landed successfully, The reaction of the Ambassador was basically "oh God - not on my watch"
No doubt Uncle Boeing's man in town had been called as well..................
It probably took the engineer 30-45 minutes to drive out to the airport which was in the sticks (relatively speaking)
