Horten 229: What is real, what is exaggeration?

[Stephan Wilkinson]

There is a photo of a test pilot wearing a höhendruckanzug. This is literally a high pressure (flight) suit with helmet. History tells us the Germans had no such suit.

You're correct in that the suit was never used, but it did exist. The Hortens had one of their employees--not clear whether or not he was a pilot--actually wear the suit and sit in the prototype's cockpit. They found that it would have been impossible for him to operate a number of the cockpit controls without extensive modification to them, so the pressure suit was never actually used.

It was indeed designed and made by Draeger, who had specialized in manufacturing deep-sea diving gear.
