59 Sqn. got two on 17Jun17 according to Comic Cuts - not bad for a poor old defenceless RE8 outfit - not clear which one was Zeumer.

1. Lts Douglas & Horton attacked and drove down an EA which burst into flames before it crashed.

2. Lt W B Hutcheson & Sgt Rose engaged an Albatros scout which opened fire at close range. After considerable manoeuvring the EA nose-dived, attempted to flatten out, but failed and crashed.
