English Channel Dover and Boulogne but later also Ramsgate (Pegwell Bay) to Calais. The journey time Dover to Boulogne was roughly 35 minutes, with six trips per day at peak times. The fastest crossing of the English Channel by a commercial car-carrying hovercraft was 22 minutes, recorded by the "Princess Anne" MCH SR-N4 Mk3 on 14 September 1995, The first aircraft to cross the Channel was a balloon in 1785, piloted by Jean Pierre François Blanchard (France) and John Jeffries (US). Louis Blériot (France) piloted the first airplane to cross in 1909. The sport of Channel swimming traces its origins to the
Hot air balloon sea level, and humidity of the air surrounding. On a warm day, a balloon cannot lift as much as on a cool day, because the temperature required for launch will exceed the maximum sustainable for nylon envelope fabric. Also, in the lower atmosphere, the lift provided by a hot air balloon decreases about 3% for each 1,000 meters (1% per 1,000 ft) of altitude gained. Standard hot air balloons are known as Montgolfier balloons and rely solely on the buoyancy of hot air provided by the burner and contained by the envelope. This style of balloon was developed by the
