CV 67 John F. Kennedy, March 2007
In early March, the aircraft carrier "John F. Kennedy", known as "Big John", took a last trip to Boston before being decommissioned. The ship is one of the last non-nuclear carriers in the fleet, and was begun in 1964. It is over 1,000 feet long, and the flight deck is over 250 feet wide. It displaces 82,000 tons, and carries a ship's company of over 3,000, an air wing of almost 2,500, and up to 85 aircraft.
Unfortunately, the line to get in was about 2.5 hours long on a cold morning, so it was a somewhat grueling experience. Security was pretty tight, with a heavily-armed guard and airport-style scanning.
