The whole issue of how commercial aviation would be handled post war in Britain commenced around 1943, both for aircraft - the Brabazon Committee - and the legal framework for international traffic. A key part of that was the provision of new airports, Croydon considered inadequate, and that, for some, required facilities for flying boats. F.G.Miles was one of the first to put forward ideas for an airport to the east of London adjacent to the Thames estuary, but in the following years others followed.
