Serious problems with British Airways' IT systems have led to thousands of passengers having their plans disrupted, after all flights from Heathrow and Gatwick were cancelled.
Passengers described "chaotic" scenes at the airports, with some criticising BA for a lack of information.
The airline has apologised, and told passengers not to come to the airport.
BA chief executive Alex Cruz said: "We believe the root cause was a power supply issue."
In a video statement released via Twitter, he added: "I am really sorry we don't have better news as yet, but I can assure you our teams are working as hard as they can to resolve these issues."
Mr Cruz said there was no evidence the computer problems were the result of a cyber attack.

If their site is large enough to have its own substation (which seems pretty likely), then they likely have a significant single point of failure right there. Substations do fail reasonably frequently and the effects can be surprising - for example I have personally lost water supply for c.1 day as a result of such a failure previously - and a water pumping station is reasonably simple to cold start. Even if they had a backup substation it would be likely to be fed from the same part of the national grid (it is very expensive to get national grid to install a backup spur from a separate part of the network if its even possible) so there is still an issue of single point of failure potentially.

The solution is usually diesel-generator backup.
But oh.. that cost money. Can't have the 20M$ yacht then.. horror!
