It was sold at auction and then restored so it can go on display as a floating museum. NEW YORK - A fireboat that took part in some of New York City's most high-profile response and rescue efforts is about to open to the public as a floating testament to history. The John D. McKean, named for Marine Engineer John D. McKean, who was burned in a gas explosion on another fireboat, went into service in 1955. In 2001, it played a major role in the response to the Sept. 11 attacks.
