An airplane of BA has lost a part shortly after take of from Schiphol Airport.
According to a spokesperson from the Dutch Safety Inspection, the so-called fairing has landed in the vicinity of Spaarnwoude. A fairing is a aerodynamic shroud of an airplane.
It is a part of an airplane that, stressed by the spokesperson, does not influence the flight safety. The part, about 50 by 150 cm in size, has not been found, so far as the spokesperson knows of. (?)
It is still unclear how the part became detached from the plane.
Anybody know about this? Was it a flap track fairing?
