Were there any other than big gun Admirals? The leadership would have been shaped by the experience of the First World War, and most of those with experience of flying would have transferred to the RAF in 1918. Or maybe the experience of the Fleet being subject to showing by Zeppelins left a view of what the Battle Fleet needed protection from?
The dual command with both the RN and RAF trying to take command does not sound like a winning plan - each could either assume the other was responsible or decide to ignore wider knowledge. I am sure that the Admirals could have killed off the carriers, but they at least realised the need for them.
If Their Lordships had been given full control from 1930 what difference could it have made?
I certainly agree with your point about dual control (but seemingly zero accountability) between the two services, which makes the achievements of the FAA during WWII all the more admirable. The RNAS's influence on the development of the RAF was enormous, as almost every mission type conducted by the RAF had its origins in the experience of the RNAS, while the RFC (unsurprisingly given their origin) really offered only Air Cooperation (CAS and reconnaissance) to the mix.
As for your final question, I'll leave that to someone who was there.
'Offering criticism on the service hierarchies that made up the Fleet, backed up by his having served in six Carriers and flown from them in all five theatres of sea warfare during five years of the Second World War, Adlam presents a highly entertaining and potentially controversial study which is sure to appeal to a wide array of aviation enthusiasts. Adlam charts the catalogue of errors that blighted the history of the Naval Air Service, which followed the disastrous decision in April 1918 to transfer the whole of the Air Service of the Royal Navy to form the new RAF. The main and over-riding criticism that the author finds with the Fleet Air Arm lies in the manner in which it was led. Adapting the oft-quoted "Lions led by Donkeys" description of the British Army, Adlam describes the activities of the Fleet Air Arm in the Second World War as the result of "Sea Eagles led by Penguins" practices, when experienced pilots were led into battle by senior members of the Navy who possessed little or no flying experience.'
