Safety Concern
If they (the TAP pilots ) truly have done this then they are indeed w@nkers of the highest order.
Not only for doing it. . . but well, what sort of rapport/cooperation do they now expect from the engineering staff, whose qualifications/contribution, they have pissed all over.
Truly woeful, if indeed true, but we, and the authorities, need some proof. . . . . I am sure you understand.
