Wow! That is fascinating gents. All of these years playing WWI sims and studying the subject - I had no idea the Tripe appeared that early. I actually smiled when I saw Dallas' name - I remember flying an RNAS campaign with him when I was a kid playing Red Baron.
I've definitely learned something new here - feels like the subject never really exhausts itself.
PS: Dallas shot my DII completely full of holes and wounded my pilot before I set down at a nearby field. Lucky to get away with that one!
