New York’s LaGuardia Airport is operating as normal again after a brief groundstop following one of the most bizarre sights seen on the New York skyline.
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.
It caused a widespread blackout with the airport reverting to backup power facilities.
Several flights were diverted and many more were delayed.
The FAA groundstop lasted less than an hour.
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.
