Heathrow warned by airlines about power supply days before shutdown | 2 April 2025 | 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. Nigel Wicking, chief executive of Heathrow Airline Operators' Committee, a group representing airlines, told MPs on Wednesday that he spoke to Heathrow twice in the week before the closure on 21 March. He questioned why the airport was closed as long as it was and why it was not more prepared considering its importance... Speaking to MPs on the transport committee, Mr. Wicking said he raised cases of "theft of wire and cable around some of the power supply" which he said temporarily took out runway lights, which are critical to passenger safety. He said he had spoken to Team Heathrow Director Thomas Woldbye on 15 March about his concerns -- six days before the fire -- and the chief operating officer and chief customer officer on 19 March -- two days before the fire.
