Crew members on board Pan American Flight 1736 flight deck were alarmed.
Pan Am Capt: Let’s get the h...out of here.
Pan Am First Officer: Yeh, he’s anxious, isn’t he.
Pan Am Flight Engineer: Yeh, after he held us up for an hour and a half...now he’s in a rush.
The words were barely out of the flight engineer’s mouth when Captain Grubbs saw a terrifying sight. Landing lights from another plane were coming straight at them.
Pan Am Capt: There he is...look at him...that...that son-of-a-b...is coming.
Pan Am First Officer: Get off! Get off! Get off!
Taking immediate evasive action, Captain Grubbs turned left and opened his throttles. Still not seeing the Pan Am 747, the KLM crew approached the
point of no return (don't miss this video)
as the jumbo jet accelerated toward disaster. Four seconds after First Officer Meurs called out "Vee one," (the go/no-go decision speed) the KLM crew realized what was about to happen.
Trying hard to avoid a near-certain collision, Captain van Zanten managed to get completely airborne as he neared exit C-4. He didn’t get high enough (the link depicts the plane’s exact altitude at the point of impact) to avoid slamming into the starboard side of the Pan Am jet. On impact, the upstairs lounge of the Pan Am jet disappeared. So did most of the top of the fuselage. (The link refers to the aircraft registrations: PH-BUF [this is the actual plane in happier times] for KLM 4508 and N736PA for Pan Am 1736.)
