A Hollywood moment in the Big Apple!

An alien invasion, E.T. the Extra-Terrestrial visiting Elliott in real life, or another plane moment?

Versions aplenty but only one reality; a transformer explosion at a power plant in Queens that temporarily lit up the New York skyline in bright blue, causing a frenzy in the city.

The explosion lit up the sky in shades of blue visible as far as Manhattan and New Jersey. The tremors shook buildings and rattled windows, sending people running into the streets.

Many on the social media said they feared an alien invasion and other conjectures, prompting the New York City Police Department to explain on Twitter that the blue light came from a “transformer explosion at a Con Ed facility in Queens” and that the fire from the explosion was under control.

“ADVISORY: The lights you have seen throughout the city appear to have been from a transformer explosion at a Con Ed facility in Queens. The fire is under control, will update as more info becomes available,” the department tweeted.

According to the New York City Fire Department, there were no injuries reported in the incident and the explosion was determined to be a non-suspicious equipment malfunction, and “no evidence of extraterrestrial activity.”

LaGuardia Airport in Queens initially grounded all flights following the explosion. No flights took off between 9.22 and 10.23 p.m. ET, according to flight tracking data company FlightAware.

Twitter users shared photos and videos of New York City’s sky. Many on the social media feared it as an alien invasion.
