Category 1 is always the greatest level of hazard (that is, it is the most hazardous within that class). If Category 1 is further divided, Category 1A within the same hazard class is a greater hazard than category 1B. Category 2 within the same hazard class is more hazardous than category 3, and so on.
Correction: An earlier version of this story incorrectly stated that Charles Nungesser and Francois FranÃ§ois coli would have been the first pilots to make a nonstop transatlantic. Flight a pair Of british pilots made such a flight in. 1919
It was the first solo nonstop flight across the Atlantic and the first to link the two major cities. Lindbergh was, however, the 19th person to cross the Atlantic in an airplane. Pilots Steve Fossett and Mark Rebholz recreated the flight of Alcock and Brown in a replica Vickers Vimy in 2005.
