With a dramatic surge of fire engulfing an electrical substation, Heathrow Airport, Europe's bustling air travel hub, plunged into chaos as operations were halted. Over 1,000 flights had to be canceled or redirected on Friday, causing significant disruptions for travelers worldwide.

Heathrow's CEO, Thomas Woldbye, characterized the event as “unprecedented,” revealing that the airport lost power comparable to a midsize city. Despite a backup transformer working adequately, it simply wasn't enough to restore full operations. However, Woldbye expressed optimism, stating they expected to be back to normal operations by Saturday.

British authorities have turned to counterterrorism police to lead the inquiry into the fire's origin, which started at a substation situated in North Hyde, northeast of the airport. Metropolitan Police later indicated that they did not view the incident as suspicious, but investigations are ongoing.

As disruptions unfolded, questions arose regarding the airport's dependency on a single electrical substation and its resilience against such crises. Although it was too early to fully tally the outage's financial implications, the event has certainly raised alarms about air travel reliability at one of the world's busiest airports.
