Includes a mid-air collision counted as one accident. Including the USSR. Figures for 1972 include three collisions each counted as one accident some unusual occurrence on Hie flight deck is that "they would never do anything about it anyway so why bother" and I have no doubt that the success or failure of any scheme for reporting operational incidents (voluntary or mandatory, anonymously or attributably) depends a great deal on the feedback to the crews. The sight of improve ments resulting directly from incident reports will go a long way to overcoming the present feeling that any report could be turned into evidence against the individual concerned. The system of confidential reporting recently introduced by the British Airline Pilots Association offers Emergency evacuation of high density passenger aircraft calls for wide exits to be provided. One of eight exits from the TriStar is seen above. The diagrams below show the type of flight and phase of flight in which fatal accidents occurred to public transport aircraft in 1972 an opportunity for real progress to be made; if with the passage of time the reports received are seen to be con structive in nature some confidence may be created. However commendable individual reporting schemes, such as the Balpa one, may be it is ultimately the national safety agencies who can ensure the fullest exchange ot information. They must be put in a position of being able to detect world-wide trends so that similar occurrences which individually may not appear significant can be correlated and the necessary warnings sounded. To be able to do so the agencies need information and resources. To avoid the number of air passenger fatalities con tinuing to rise annually in step with the increasing traffic the actual number of accidents must be reduced. The art of air safety has advanced to the point where tfris will only be possible by the most painstaking attention to detail for it now seems that the small causal factors in accidents are often of the greatest significance.
