My great Uncle was shot down and killed by one of the members of Jagdstaffel 11 on 13 April 1917, a scant 5 days before Richtofen's death. He was an observer in one of the six R.E.8s from No. 59 Squadron RFC sent on a long range photo reconnaissance mission. The R.E.8s missed their intended escorts, and were met by the picked fighter pilots of Jasta 11, who shot them all down within five minutes.
