British Interplanetary Society 1930's Moon Mission: WHAT IF…?

According to Wikipedia, the British Interplanetary Society (founded in 1933 by P E Cleator), is the oldest organisation in the world whose aim is exclusively to support and promote astronautics and space exploration. It is a non-profit organisation with headquarters in London and is financed by members’ contributions.

In the late 1930s, the group devised a project of landing people on the moon by a multistage rocket, each stage of which would have many narrow solid-fuel rockets. Their lander was gumdrop-shaped but otherwise quite like NASA’s Lunar Module.

Sadly, their detailed proposal was flawed and “HMS Moon Rocket” as it was dubbed would not have made it into earth orbit, but what if?

Now imagine, it’s 1939 and Britain is heading for war. Concerned about the conquering exploits of Germany, the UK Government decided to fund the building of a rocket ship to the moon.

Now a question for those who frequent this forum, who would have been the most likely crew? I understand that there would have been three astronauts, but who would the British Interplanetary Society have chosen? Who were the leading explorers or pilots from the late 1930s and who might have been chosen? Any suggestions? Discuss…
