I am baffled by the Admiralty promoting and facilitating these newsreels, as it shamelessly shows that an immersion suit that was NOT available to the Truculent escapees, many of whom would likely have survived if it had been!
Richard Compton-Hall has combined research with his own experience as a submariner to provide an insight into the inventions and motivations of the early submarine pioneers.
This study explodes a number of popular myths, such as the claim that David Bushnell's one-man Turtle chased the British fleet out of New York Harbour in 1776.
The truth about underwater exploration, however, is stranger than the fiction, not least because of its secrets and brotherhoods, duplicity and deception, determination and despair, frequent failure and rare triumph.
