Hi!
Here is what I found in
Under the Guns of the German Aces:
"Eventually he (Lothar) was successful in securing a job as a civil pilot with Deutsche Luft-Reederei, mainly flying mail and passengers daily between Berlin an Hamburg... on 4 July 1922, he was approaching Hamburg on a routine flight when his engine failed. Lothar was piloting a converted LVG C VI, a former bomber aircraft that had been adepted for passenger and light cargo use. On this occasion he was carrying two passengers, the american silent screen actress, Fern Andra and her business manager. He had made forced landings before and was probably not too alarmed at the prospect of another, but the terrain was rough and wooded and as he came in he clipped the top of a row of trees which tipped the machine nose down and over on its back. Help was not long in coming and first, the two seriously injured passengers were helped from the wreck. The recuers turned next to Lothar, carefully extricating him, still barely alive, from the smashed machine, only for him to die later in the ambulance carrying him to hospital.
