Flock of birds or weather balloon may have caused White House lockdown, officials say

The White House was on lockdown Tuesday morning and fighter jets were assembled for a potential airspace violation, but it ended up being a false alarm, officials say.

Turns out, the alert could’ve been triggered by a flock of birds or a weather balloon, media outlets report.

An evacuation order was also in effect for about 30 minutes at the U.S. Capitol, WJLA reported. Early reports pointed to a possible small jet craft in the airspace.

The White House was locked down this morning due to a potential violation of the restricted airspace in the National Capital Region,” Secret Service spokesman told WRC. “The lockdown has been lifted at this time.”

But NORAD confirmed just before 1 p.m. it was a false alarm.

“NORAD responded to an event in the Special Flight Rules Area surrounding Washington D.C. this morning,” the agency tweeted. “NORAD directed @USCG rotary wing aircraft to investigate and the event was resolved without incident.”

It might have been a flock of birds on the radar, ABC11’s Sam Sweeney reported.

A NORAD spokesman said the unidentified object could have been “a flock of birds or a weather balloon,” NBC News reported. But another spokesman wouldn’t “confirm or deny that it was a flock of birds,” Gizmodo reported.

“A trained radar operator should be able to differentiate between a flock of birds and an aircraft, but this mistake is actually a fairly common one,” retired Air Force Col. Cedric Leighton told CNN. “How the flock of birds appears on a radar screen can be very similar to the radar ‘look’ of a small aircraft.”
