He had never seen anything like this before
But what Jason announced to the passengers was far from the truth. Birds do not normally behave this way. In his years working as a pilot, he never had seen birds attack a plane like this before. Jason told Jimmy to call flight control and ask for help.

The number of birds coming at the plane was increasing and they were getting more violent. Jason feared that it was only a matter of time before the birds would ruin the engines. But there was another problem.
He could not control the plane
Jimmy said he could not reach flight control. Nobody was answering. Jason told him to keep on trying. Jason then instructed the cabin crew to calm the passengers down. The passengers could barely see anything out the windows because there were too many birds.

Their presence darkened the whole plane, making the passengers more terrified. Jason tried to gain altitude with the plane. The number of birds was extremely high that the sheer volume of their presence was making the plane steer down.
