If you are able to get a copy I would suggest The Scarlet Angel by Alban Ali.This is the story of a seven-thousand mile journey from India to the UK, mostly a Comper Swift. The book was first published in 1934 by Duckworth. My copy took 5 years to find! You wont find any copies in the UK library system. Well worth the search though.
Then there is Adventure with Fate by Harald Penrose. Why not try The Flight of the Mew Gull by Alex Henshaw.If you want a First World War book there is the classic Sagittarius Rising by Cecil Lewis.
You may note that all these works are non-fiction.
