John F. Kennedy 13L Grass Runway Takeoff

When selecting Runway 13L for takeoff at John F. Kennedy during the day, there is an entry point on Runway 22R: 22R/4L. If selected, the aircraft will fly straight

directly across Runway 22R and take off from the grassy area next to Runway 13L; during the final acceleration phase, the aircraft will sink into the ground, and it will spin before clearing the runway.
