The driver who struck a 68-year-old man in Midwood yesterday fled the scene with his head out the side window because his windshield shattered from the impact with the pedestrian.

Witnesses tell the Post that the victim, Allan Halter, was crossing the intersection at Avenue O and Ocean Parkway when he was hit by a Buick sedan, later found to be driven by 47-year-old Michael Spalla. “He just flew up in the air and that was it. He landed like 50 feet in front [of the car]," one bystander said of the collission. “The guy stopped and then just took off. His head was hanging out the window and he was driving with one hand.”

Another driver who saw Halter get hit followed Spalla and took pictures as he ran through red lights and swerved in and out of traffic to evade the scene.

Police eventually pulled Spalla over and arrested him. According to an NYPD spokesman, Spalla, a Hollis Hills resident, is charged with aggravated unlicensed operation of a vehicle and leaving the scene of a serious accident.

Halter remains in critical condition at Lutheran Medical Center.
