Hey Mike,
Good find on the flight record data. Shaheed's definitely been through this airfield a ton and the records have some rather incriminating evidence about some other visitors to the airfield - I'll fill you in after I've researched them some more.
Anyway, with the bug in place, we should be able to intercept Shaheed next time he's inbound.
