I had an engine stop during an EOL on my b47 conversion as a 200hr rookie- at maybe 500'. A bit of a surprise to find the controls suddenly heavy but as others said above you just do it, worked fine - greaser! I told the instructor the hydraulics had failed and he said nonsense - we realized the problem in the ensuing silence...
Hardly a bright bit of design, but as the '47 was one of the very first they just hadnt thought about everything then, had they? Thats why people love it, its right back to the pioneering stuff in a 47. You'd be flying a Bleriot or similar to find that level of design experience in a plank...
