Heathrow closure: what caused the fire and why did it bring down the whole airport?

The closure of Heathrow Airport has caused chaos, leaving thousands of passengers stranded. More than 1,300 flights have been affected, about 120 of these were already in the air.

A panel of experts offer their insights – and consider the implications of such a major incident.

Airports should implement disaster recovery procedures for at least these reasons:
* Ensure passenger and staff safety.
* Maintain operational continuity.
* Protect critical infrastructure.
* Facilitate emergency response.
* Minimise financial losses.
* Comply with regulations.

Got it #HEATHROW?

The #Energy Secretary has commissioned the National Energy System Operator (NESO) to investigate the power outage that disrupted #Heathrow #Airport and the surrounding area. This follows restoration of power to all affected customers. The investigation aims to understand the incident’s causes and improve the UK’s energy resilience. The government is committed to preventing future disruptions through its Plan for Change, which includes boosting energy security. Energy Secretary Ed Miliband emphasised the importance of learning from the incident to protect critical national infrastructure. NESO will collaborate with stakeholders, including Heathrow, to ensure a thorough review. Initial findings are expected within six weeks.

A little investigation reveals that perhaps 25% of #Heathrow activity isn't completely useless. Most is simply boredom expressed as kilograms of Jet A converted into kilograms of CO2.

Anyway, restless folk with itchy feet becoming angry because the choices they made resulted in non-existential inconvenience are critical to politicians, so here we are, facing an exaggerated crisis.

If Heathrow was appropriately sized it would certainly be easier to maintain.

Good afternoon. It's 3PM, Saturday, 22nd March. The headlines: #Heathrow #Airport resumes full operations following an unprecedented shutdown caused by a power station blaze, affecting over 1,350 flights. The incident, which led to diversions across Europe, is not deemed suspicious by officials. The Comic Relief telethon has garnered £34m and #boxing icon George Foreman has died aged 76. Three rockets have been launched towards #Israel from southern #Lebanon. #BBC #News

Good afternoon. It's 12PM, Saturday, 22nd March. The headlines: #Heathrow Airport is back in service after a power station blaze led to its most extensive shutdown in years, affecting over 1,350 flights. Authorities do not suspect foul play. #Israel escalates its #Gaza campaign, with the military instructed to expand control as casualties near 50,000 and Gaza faces a 19-day blockade. #BBC #News

The closure of #Heathrow yesterday had 200,000 people not flying. If each flight had a climate impact of 1 tCO2 equivalent, then this would be 200,000 tCO2eq of emissions that didn't happen.

A study showed that for every ~4400 tCO2eq one human will die from climate change impact until the year 2100.

200,000/4400=45

Every day of Heathrow operation will kill 45 people in the future. Yesterday saved 45 people's lives.

I wouldn't want to be among the people who now need to explain why there is a single-point-of-failure for critical infrastructure. It might have looked like an acceptable risk at the time. After the fact it looks like a foolish decision.

I'd expect that other subsystems will be scrutinized as well. This looks like a higher level problem.

Heathrow flights have resumed: What we know so far.

Flights have resumed at Heathrow Airport, a day after a fire at a nearby electrical substation shut down operations at one of the world's major transport hubs.

Heathrow, the UK's busiest airport, said on Saturday morning it was open and fully operational, however flight disruptions are expected to last days.

Since my post yesterday about the Heathrow fire "did numbers", as the influencers say, I just wanted to use the opportunity to say:

The power's back on now, and that's no doubt thanks to the hard work and dedication of some hugely skilled workers at National Grid. I hope everyone can spare a thought for them, as I don't doubt this has been a very rough 24 hours.

Good morning. It's 9AM, Saturday, 22nd March. The headlines: Boxing legend George Foreman has died aged 76. #Heathrow Airport resumes normal service after a brief halt, prioritising European flight redirections. The Tate brothers have been extradited to Romania. #Israel escalates its #Gaza offensive, launching renewed ground attacks and ordering the military to expand territorial control. #BBC #News

Ruth Cadbury MP, chair of 🇬🇧 House of Commons transport committee, said they would quiz the companies involved “once the dust settles”, adding: “We need to ask serious questions about resilience and how we can ensure nothing like this happens again at #Heathrow or other airports.” #fire #CNI #resilience
