There is no evidence that asaistance from such stations was requested. From the authorizations issued by the Milan A60 and the oomnunmations exchanged between the aircraft and that control office, it appears that the plane plotted its navigation by utilizing first the Saronno and. then the Biella radio beams. During the flight of the Super Constellation, those nangational ends were in uninterrupted operation.
