How did Heathrow used to look ?
I haven't been through the entire thread but thus far I have not seen reference to the BEA Viscount (G-AMOK) which suffered an incident on the disused 15 Central in 1955. In low visibility the aircraft was instructed to line-up on 15R as it taxyed along the northern taxyway. On reaching 15 Central the crew mistook it for 15R and lined up on it. During the take-off roll the aircraft crashed into WIP along the runway resulting in just a few minor injuries to the aircraft's occupants.
