Presumably you would also classify as "stupid" crews that
still signed for it and flew
an aircraft whose functional anti-collision lights were replaced with dysfunctional HISL's in that in cloud, haze or low over water they dazzled the pilots with reflection? Or was the SOP to switch them off in the very conditions that they were most needed an indication of the superiority of the FAA over the RAF? Or did the fault lie rather with the higher command that supplied them with yet another example of unairworthy aircraft?
