David Pinsent

[jeroen]

Looking for information on Wittgenstein I found that his friend David Pinsent, became a pilot, was possible found unfit for active service at the front an became a military tespilot, but died after a crash may 8th, 1918.

Who can tell more about his flying career and military service of David Pinsent?
Did he correspond with Wittgenstein during WW1?
