Research and various other reasons' behind hullabaloo - but why didn't someone say that a month ago? Time to pack it up and go home, drone conspiracy theorists: The White House has finally offered an explanation for those mysterious New Jersey drone sightings from late last year - though its rather vague statement raises more questions than it answers.

Less than a day after the deadly collision of American Airlines 5342 and a US Army Blackhawk helicopter killed 67 people over the Potomac River, President Donald Trump said common sense already told him what to blame: diversity programs creating a class of unqualified federal workers.

The unexplained, SUV-sized drones that caused a stir flying over the areas in the Northeast in November and December have returned. As of Sunday, Jan. 25.

A massive emergency response remains on scene of an aircraft crash in the water near Reagan National Airport. A military helicopter and a regional jet with 64 people on board collided mid-air Wednesday night.

"This was not the enemy," press secretary Karoline Leavitt said, attributing the statement to President Donald Trump.

Research company Enigma Labs said it has tallied 650 sightings nationally described as drone-related since November, with most concentrated in the Northeast.

On social media, users shared theories that range from foreign interference to UFOs to hobbyist activity. The FBI and Department of Homeland Security said there was no evidence" the reported drone sightings posed a threat to national security or public safety or had any foreign connection.

Investigations have begun into how American Airlines flight 5342 suffered a mid-air collision with a US army’s Black Hawk helicopter, with both crashing into the Potomac River in Washington. Aviation experts are already providing some explanation as to how this tragedy unfolded,

Sixty passengers and four crew members from the plane and three Black Hawk helicopter personnel are feared dead as a recovery mission is underway.

Officials say there are no survivors among the 67 passengers on the aircrafts that collided above Washington, D.C.
