President Donald Trump early Thursday lamented the midair collision that occurred over Washington D.C. and raised serious concerns over how such a crash could occur.

“The airplane was on a perfect and routine line of approach to the airport. The helicopter was going straight at the airplane for an extended period of time,” he wrote in a post on his Truth Social account. “It is a CLEAR NIGHT, the lights on the plane were blazing, why didn’t the helicopter go up or down, or turn?

“Why didn’t the control tower tell the helicopter what to do instead of asking if they saw the plane,” he added. “This is a bad situation that looks like it should have been prevented. NOT GOOD!!!”

Trump reacted after an American Airlines jet collided with an Army Blackhawk helicopter near Reagan National Airport on Wednesday evening.

Earlier, Trump expressed sorrow for the victims and the country.

“What a terrible night this has been. God bless you all!” he wrote.
