"I found a spot that didn't have cars right underneath me and went for it," he said. "You don't have too much choice, because you can't go back up."
Once they were on the ground, Gheysar said he rolled the plane over to the right-hand shoulder to get it out of the way as much as possible.
No cars were hit and no one was injured. Gheysar said he was amazed to see traffic continued to flow in the far lane.
A Dodge Dakota later clipped one of the plane's wings. Gheysar said it appeared the driver was pulling over to check out the plane with its flashing lights, and maybe misjudged the length of the wings. The driver could not be reached for comment. The motorist was not injured and his truck suffered minor damage.
