ex-BA
When I first joined BA, there were stickers on doors in Speedbird House
"Heathrow must thrive, build Terminal 5"
That was - honestly - 21 years ago.
Oh dear.
But IMO the real test comes now. After a day of chaos, let's hope the problems have been analysed, baggage systems rebooted, contingency plans up and running so everything reaches normality before end of play Friday.
