Over and Above was first published in 1919, soon after John Everard Gurdo had been invalided out of the RAF. This new edition retains exactly the original script but has been updated with an introduction by John Gurdon's granddaughter Camilla Jane Gurdon Blakely and an extended illustrated appendix by renowned historian Norman Franks.
