Sir - In early December 1994, a Boeing 737-400 returned to its Istanbul base after completion of a charter service to Stockholm Arlanda.

The flight was considered uneventful by the crew, who were surprised, therefore, by the news that the aircraft's leading edge, at a point just outboard of the engine, was contaminated by crabs' legs. How did these limbs come to be so firmly attached to the aircraft? There were no handling difficulties reported during the course of the flight.

I hope that the dissemination of this safety-related information is of interest to all parties concerned with the continuing task of achieving greater levels of safety in aviation.

Has anyone else caught a crab in this way?
