Pardon?
It took the Captain of BA Flight 9 (volcanic ash over Indonesia) eleven years to find out from declassified information that satellite monitoring stations in Australia and Guam were following his flight.
Capt Moody's comment? "We don't know what they're watching."
I'm not sure why you would be expecting anything different in this case if more were known from confidential sources.
"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."
Indeed, they contacted Moody within 15 minutes of landing. I wonder if remote telemetry/diagnostics of systems has been in heavy A/C since the late 70s?
