21st Novemner 1989 when BA 747-100 G-AWNO missed the Penta hotel at Heathrow by a matter 12 feet after electing to execute a go around. I was working at LHR at the time, while walking around the airport perimeter that very day it was difficult to see cars on the road.
Almost a truly catastrophic day.
Sadly, Capt Stewart was scapegoated and later committed suicide.
A story worth reading.
