German Reconnaissance information

Hello,

For my first message in the forum I will try to well write english

My question is in relation with a German Reconnaissance group. In August 16th 1918 close to Havrincourt the plane of Leutnant Thierron Emil and Saurwein Friedrich was shot. Saurwein was kill but Thierron bring back his plane but died two days latter. They are both buried in the Cambrai's german cemetery.

I would like to get several information about :
- which kind of plane they used at this time? (I would like to build the kit if it's possible)
- how the Reconnaisance group were organised in the German army? Apparently they were in the FA-9 but I have very few information about it.
- Is anybody know which allied pilot fight with them during 16th August 1918?

Thanks a lot for your help,

Val
