The JetBlue Airbus 320, bound for West Palm Beach, Florida, took off 10,000 feet short of the plows Tuesday, then cleared the runway nearly 1,000 feet above them. No injuries were reported.
FAA spokesman Jim Peters said the incident is classified as a "runway incursion." ..............
I would hate to see what 5 snow-ploughs would do to an A320. BTW is there a runway that long at JFK?
