Tenerife in 1977 was the KLM going with only having been given a departure clearance and not a takeoff clearance.
Due to it being a small airport, the a/c had to back-taxi. KLM blocked access where Pan-Am could not get past without collision. Therefore, Pan Am had to wait for KLM to finish taking on a full fuel-load. The KLM pilot made that decision, too.
KLM backtaxiied down the runway. Pan Am was to pull off and come up behind him. The controller told Pan Am to pull off on the 3rd accessway but it was 135 degrees to the left. The controller probably forgot about the back taxi (IMHO).
The 4th accessway would have been smooth and brought Pan Am up near KLM’s tail. The (dead) KLM pilot already tried to roll without authorization and was shut down by the co-pilot. Now he’s mad and embarrassed. Next time he rolls but Pan Am is not clear of the runway. When he finally sees Pan Am through the fog, it’s too late.
The runway under construction happened in the far east as I recall. Singapore Airlines(?). The 747 was taking off in heavy rain and accidentally chose the wrong runway. Yes, one under repairs. The a/c struck equipment parked on the runway overnight (it was a night takeoff attempt).
