What we learnt from travel chaos and how could it be prevented? - It takes 10 hours to restore key airport systems if they lose power, MPs on the Transport Select Committee were told

The boss of Heathrow Airport has apologised to the over 200,000 passengers whose journeys were disrupted by its closure last month following a fire. Thomas Woldbye offered his "deepest regrets" adding that the "situation was unprecedented".

The boss of Heathrow came under fire for an 18-hour shutdown at the airport last month after an airline representative said he had raised concerns about the hub's resilience days earlier, as lawmakers scrutinised the nationally embarrassing incident.

Heathrow Airport was warned about the "resilience" of its power supply in the days before a fire which shut down the airport for more than a day last month.

The official said he had raised concerns about Heathrow’s electricity supply days before a power outage forced it to shut down. Heathrow disputed the relevance of the official’s comments.

London Heathrow Airport was warned about possible issues with its power supplies a few days before a nearby fire cut electricity to the hub and forced Europe’s busiest airport into an unprecedented day-long blackout.
