IFF is standard fit on all aircraft, Mil and Civ. A 'Gripe sheet' is also standard, how else would the ground crew whats was tits up?
Looking at the images of the jet, it appears that the compresser section of the engine let go, which would have then taken out the combustion and turbine sections, bye, bye engine cowlings! It also looks like like some engine parts went though the mainplane, so some poor bugger has one hell of a Cat 3 to play with!
(My Cat 3Q may have expired, but give me a big pile of rivets and a few sheets of ally, I can fix most things!)
