It says on the BFS ATIS that crews should be aware of Langford Lodge on approach to 07. Also it would be odd that neither the approach or tower controller would have failed to notice the lower than usual altitude on final. Also the DME would have been wrong and there are no lights/PAPI's at Langford Lodge.
Saying that its not impossible for it to have happened, as we all should recall RYR9884 landing at Ballykelly a good 5 miles east of LDY!
