As far as I am aware, FAA regulations that govern most of the air traffic and safety procedure prohibit the presence of any person in the cockpit particularly during take off and landing. I wonder if the ex MD of Biman was not aware of this! Or may be CAB flight safety regulations probably adopted from FAA, ignores this aspect of flight safety. Could some knowledgeable source clarify this matter?

Another point is related to the runway. As the runway and surroundings were covered under rain water, was there any marker on both sides of the runway visible from the control tower showing the runway path? Also was the minimum touchdown marks on the runway visible from the control tower? If the answer is negative, then permission to land should have been denied by the control tower. If the answer is affirmative, and visibility also confirmed by the flight commander, then it is the commander's responsibility.

Undercarriage malfunction, locked brakes, wheel malfunction or error of judgement could possibly be one of the reasons for the accident. However, all this will come out during the enquiry which should reinforce cockpit discipline particularly during take off and landing. I believe on a number of occasions, this discipline has been violated earlier without any one being aware of it particularly by persons of responsibility, who were allowed unauthorised access during landing or take off as the flight commander felt embarrassed due to the presence of the VIP. CAB may well look into this matter in detail, particularly as there was an unauthorised person during this tragic landing.
