The Boing 737 — which was scheduled to depart for Montego Bay, Jamaica at 9:15 a.m. — slid for about 10 seconds before coming to a rest, said the passenger, Charlie Simmons, 50, of Reisterstown.

Bwi Airport spokesman Jonathan Dean noted that the plane’s wheels never left the Taxiway.

But he confirmed the plane remains stopped on Taxiway P, and that airport operations employees, fire department, Maryland Transportation Authority Police and Southwest Airlines personnel “responded to the incident scene.”

It was evacuated, and passengers were brought back inside the airport, Dean said.

Skid marks on the taxiway pavement could be seen in a photo Simmons took of the plane.

All the surfaces in the airfield had been chemically treated to prevent ice from accumulating from the overnight mixed precipitation, and surface temperature was measured at 37 degrees Wednesday morning, Dean said.

Simmons and his wife, Laura, both attorneys, had been headed on a Jamaican vacation.
