There is one thing I don't get, though. If the helicopter was spotted in 1995, why did it take until 1999 to recover it? I'm just curious.
First of all the helicopter spotted IT (the bomber wreckage), not the other way around.
My guesses on the reasons for the delay are:
1) Suharto was still in power in 1995, and I think his successor, Megawati Sukarnoputri, took power in 1999 or thereabout.
The recovery of American bodies was probably very low on the dictator Suharto's "to-do" list.
2) The area is probably VERY remote.
