The closure of Heathrow, Europe’s busiest airport, due to a fire at a nearby electrical substation dominates the front pages of British newspapers on Saturday, with more than 1,350 flights cancelled and journeys disrupted for hundreds of thousands of passengers.

The Guardian splashes with “Chaos and anger as fire shuts Heathrow airport”, above a picture of anxious travellers, and an article that focuses on Downing Street’s reaction: that there are “questions to answer” as to how a power failure could cause such disruption.

The Times leans into the blame narrative with “Heathrow chaos puts bosses in firing line”, elaborating in its subheading with “Holidays ruined” and “Travellers stranded abroad”.

The Daily Telegraph calls it the “Colossal failure of Heathrow blackout” next to a photo of the secretary of state for energy, Ed Miliband, who, as the subheading explains, “admits site looks ‘vulnerable’”.

The Mirror sums it up with one word – “Grounded” – splashed above a photo of the fire helpfully captioned as an “inferno” and another of a teary passenger. “Fire sparks travel chaos,” the strapline says, and “Boss admits airport can’t be run on backup” is further down.

The Daily Mail strikes an incredulous tone – “Farcical!” – pointing out that the “WHOLE of Heathrow is brought to a standstill by ONE electrical fire”. The article runs the common thread of “Heathrow bosses” having questions to answer as to “how a small fire shut down one of the world’s busiest airports”.

The Financial Times throws it forward with a headline that warns “Travellers face days of disruption”, while the subheading also points to “Doubts over resilience”.

The i also looks ahead, warning “Heathrow chaos to last ‘for days’ as fire exposes UK weaknesses”.
