New York’s LaGuardia Airport is operating as normal again after an electrical fire caused the city’s iconic skyline to turn blue and created a widespread blackout.
A transformer exploded at a Consolidated Edison Inc electrical plant, resulting in a huge bright blue light in the sky.
It sparked a fire, which was soon under control.
"There was a brief electrical fire at our substation on 20th Avenue & 32nd Street in Astoria this evening, which caused a transmission dip in the area. All power lines serving the area are in service and the system is stable," ConEdison tweeted.
The airport, in Queens, was one of the organisations affected and it had to revert to backup power facilities.
Several flights were diverted and many more were delayed.
In addition, the Metropolitan Transportation Authority said there were ‘extensive delays’ of local train services.
The bright blue flame sparked frenzied activity on social media with alien invasion theories particularly rampant.
The Fire Department said there were no reports of injuries or major damage.
