flight jackets. Even when the fur was replaced with wool, this coat was warm enough to keep Lt. John A. Macready warm when he set a world record in April 1921, reaching an altitude of 40,000 feet in his open-cockpit airplane. Styles range from the B-3 "bomber jacket", to the M-445, the U.S. Navy's shearling jacket. Also popular in the military were, and still are, synthetic jackets. These jackets first gained esteem after General Hap Arnold rejected the A-2 jacket in 1942. Styles range from the cotton twill B-series to the standardized jacket of the U.S. Navy, the CWU-series. Both synthetic and shearling jackets are worn and collected by army buffs today, but neither has the historical status of the A-2 jacket or the G-1. Today, flight jackets are usually associated with the MA-1, a now-obsolete U.S. military jacket, which is mostly found in sage green. It is made with flight silk nylon and usually has a blaze orange lining, with the specification tag in the pocket, though earlier models had a sage-green lining and the specification tag on the neck area. It has two slanted flap pockets on the front, two inner pockets, and a zipped pocket with pen holders on the left sleeve. The lighter weight version of the MA-1 is known as the L-2B flight jacket, which in turn, replaced both the original L2 and L2A jackets, which all three differ from the MA-1 as they have snap-down epaulets and no inside pockets. The military flight jackets currently used today are the CWU-45P (for colder weather) and the CWU-36P (for warmer weather); both are made from Nomex. Civilian uses In the 1970s and 1990s, flight jackets became popular with scooterboys and skinheads. In the 1980s, a baseball style bomber jacket became popular. In 1993, a uniform flight jacket was worn as the "national costume" of the United States for the APEC meeting held in Seattle, Washington. In the early 2000s, the bomber jacket was popular casual wear in hip-hop fashion. The jacket has also caught on with several police departments across the United States for its sturdy design and heavy insulation. Flight jacket has had a resurgence in popularity during the 2010s in street fashion, and is a notable staple of celebrities such as Kanye West.
