Many a times,the 'black box' or FDR is destroyed or end up in the ocean bed making it difficult to get information. Instead of housing Flight Data Recorder and voice recorder in the aircraft it should be removed from aircraft and a live DATA transmitted from plane to control towers en route. This way the DATA will be recorded till the last moment at the nearest tower. If no incident happens in a given period, the recordings can be erased. With present day technology, identifying aircraft and recording details shouldn't be a problem.If NASA knows how their rockets are doing millions of miles away, recording Flight Data should be easy.
