The rate of fatal air cargo accidents is apparently eight times higher than for passenger flights. The data, from a new study by the UK Civil Aviation Authority, is based on the number of flights flown, but the rate is still seven times greater when using hours flown as the rate of measure. Pilots flying freight only aeroplanes in the USA are exempted from new rules restricting how many hours passenger airlines can fly. Pilots’ unions have been asking for the same regulations to apply to the air cargo industry, especially in the face of a second fatal accident to a cargo plane in the USA this year. The freighter broke apart and burst into flames, killing two pilots.
