The following was posted on The Aerodrome;

On 2 April 1918, 2nd Lt Ernest David Jones and 2nd Lt Robert Francis Newton, No 52 Sqn, were shot down and killed in RE8 A3868, the 75th victory credited to Manfred von Richthofen. The date of the deaths of these two has also been recorded as 3 April – most likely the result of being reported late in the day. Why they shoud have been reported as an F2b crew is a bit of a mystery.

So it appears the author spelt Jones’ name wrong, and for some bizarre reason managed to confuse an RE8 of 52 Squadron with a Bristol of 22. Certainly worrying about information in the rest of the book
