In the early 1970s, National Foam, Inc. invented alcohol-resistant AFFF technology. AR-AFFF is a synthetic foam developed for both hydrocarbon and polar-solvent materials. Polar solvents are combustible liquids that destroy conventional fire-fighting foam.
1963 The United States Navy scientists began to work with 3M to develop aqueous film-forming foams (AFFF). The US military began to use AFFF since its development in 1963 and patented AFFF in 1967. [22] [23] 1961 A DuPont in-house toxicologist said C8 was toxic and should be "handled with extreme care." [10]
AFFF was developed in the 1960s under Project Light Water in a joint venture between 3M and the U.S. Navy. AFFF forms a film that floats out before the foam blanket, sealing the surface and smothering the fire by excluding oxygen. AFFF is widely used for ARFF firefighting at airports, often in conjunction with purple-K dry chemical.

Display of inductees in the National Inventors Hall of Fame in Alexandria. The National Inventors Hall of Fame is an American not-for-profit organization, founded in 1973, which recognizes individual engineers and inventors who hold a U.S. patent of significant technology.
The names listed in the following tables, unless otherwise noted, represent the most current top 10 breakdowns of what newborn children are commonly being named in the various regions of the world. This is a dynamic list and may never be able to satisfy particular standards for completeness.
This list does not include fictional aircraft or concepts that were abandoned before a prototype was built. In the US Air Force the naming convention for fighter aircraft is a prefix "F-", followed by a number, ground attack aircraft are prefixed with “A-” and bombers with “B-”.
