But itīs not a question of being able to see or not to see your wing tips. Itīs a question of situational awareness and good airmanship. Although the 145 was not "right in front of them" it was most evidently outside the designated clearance area. I still go by my theory that they (747) assumed it would be clear and got caught when the (145) stopped unexpectedly short (most probably on ramp frequency and not ATC frequency at that point).
