C1,
Verry Interesting but.......
Air Mephis took the 2 ex Royal Jordanian 707F
They bent the first one some months ago ( no details at the moment)
They then took the one that just bent in CAI from somewhere else.
They are now in AMM getting the second ex RJ up and running.
The 2 RJ aircraft were Stage 2 but the one last week in CAI was Stage 3
