Rozière balloon days or even weeks. The first Rozière was built for an attempt at crossing the English Channel on 15 June 1785. The balloon suddenly deflated (without the envelope catching fire) and crashed near Wimereux in the Pas-de-Calais, killing Rozier, who was riding the balloon. Presently, Rozière designs use non-flammable helium rather than hydrogen. Their primary application is for extremely long duration flights. The first successful Atlantic crossing was made 31 August to 2 September 1986, Newfoundland to the Netherlands, by Brink, Brink and Hageman in the balloon "Dutch Viking". During February 1992, the first east-to-west Atlantic crossing was achieved by
Hot air balloon landing. Some hot air balloons have "turning vents", which are side vents that, when opened, cause the balloon to rotate. Such vents are particularly useful for balloons with rectangular baskets, to facilitate aligning the wider side of the basket for landing. The most common type of top vent is a disk-shaped flap of fabric called a "parachute vent", invented by Tracy Barnes. The fabric is connected around its edge to a set of "vent lines" that converge in the center. (The arrangement of fabric and lines roughly resembles a parachute—thus the name.) These "vent lines" are themselves connected to a
