Gerhard,
Plate is from that actual aircraft. It is part of the wing or flap. Part is still in the village nearby where aircraft crashed. Also some other parts were found but they were incorporated in tools, sheds and so on (piston made use as a hammer). Some small parts were also found on location.
Also some witnesses are still alive and they remember crash very well.
I have some information about the crash but I am still searching for the names of 12 passengers, data about the flight (from where it came and where it was going), and general thing s about TG4 unit.
