Heathrow Airport was warned about the "resilience" of its power supply in the days before a fire which shut down the airport for over a day last month. Nigel Wicking, chief executive of the Heathrow Airline Operators' Committee, told a group of MPs on Wednesday that he spoke to the Team Heathrow director on 15 March about his concerns.
