All About London's Heathrow Airport, Shut After Electric Substation Fire

Britain's Heathrow Airport, a major travel hub, said it would be closed all of Friday after a huge fire at a nearby electrical substation wiped out power, disrupting flight schedules around the world.

Here are some facts about one of the world's busiest international airport:

History:

-- The airport is named after the village or hamlet of Heathrow, which used to be roughly where Terminal 3 now stands.

-- It began as a tented village in 1946 serving 18 destinations with a handful of airlines making 9,000 flights a year.

-- The first departure was on New Year's Day 1946 to Buenos Aires via Lisbon, the first refuelling stop on a long-haul flight to open up Britain's first air link with South America.

-- Heathrow's first terminal for short haul flights opened in 1955. Originally known as the Europa Building, it is now known as Terminal 2.

-- Terminal 1 was formally opened in 1969 by Queen Elizabeth and was closed in June 2015. Terminal 3 opened in 1961 and Terminal 4 in 1986.

-- Terminal 5 opened in 2008. The public inquiry into its construction was the longest in British planning history, lasting nearly four years.

Key Numbers:

-- Heathrow serves over 230 destinations in nearly 90 countries.

-- 90 airlines have made Heathrow their base, including British Airways, Virgin Atlantic and Lufthansa.

-- There are two main runways. The northern one is 3,902 metres long. The southern is 3,658 metres.

-- The airport will submit its proposal for a third runway this summer, weeks after the British government granted its support to the project citing its potential to boost trade and economic growth.

-- According to the group's traffic summary, 5.7 million passengers travelled through Heathrow in February 2025, making it the busiest February on record. Passenger numbers amounted to 84.1 million from March 2024 to February 2025.

-- Heathrow is operating at 99% capacity and risks being overtaken by European rivals. Its two runways compare with four each at Paris' Charles de Gaulle and Frankfurt Airport, and six at Amsterdam's Schiphol.

-- There are around 475,000 total aircraft movements annually.

-- The most popular destination is New York.

-- Over 90,000 people work at the airport, the UK's largest single-site employer.
