This edition of Transactions of the NDS provides an excellent picture of early naval aviation and its role in the defence of HM Dockyards. Articles include Royal Naval Air Stations around the British coast, particularly those at Calshot, Lee-on-Solent and The Solent. Anti-Zeppelin Experiments are covered and historian Philip MacDougall writes on how Lord Trenchard, in the early years of the RAF, suppressed Royal Navy's Marine Aircraft Experimental Establishments as there was a fear that, in the years after the First World War, the RAF feared its being abolished and returned to Navy and Army control. What a great story early naval aviation is! ( )
