Subject: Telegraph Operations Aloft
I changed the subject line in my reply to you. "Aerial Telegraphy USMT" as the USMT never practiced such. Only signalmen used flags in aerial telegraphy. USMT Ops employed wire or electric telegraphy. >wink (18.104.22.168.?)
Airborne wire telegraphers were said to have used what was then called a metallic circuit (today we call this a hard wired loop) as there was no way the gain a (single wire) common ground return using a spike driven into moist earth to make a connection.
The "Operations" section in F. Stansbury Haydon's, "Military Ballooning During the Early Civil War" may have what you are looking for.
I'm not familiar with balloons and lightning strikes. I do know that the effects of lightning strikes are discussed beginning on page 295 of Geo. B. Prescott's 1860 publication, "History, Theory and Practice of the Electric Telegraph".

For further assistance, you may also wish which to contact aeronaut & SCARD associate Kevin Knapp via this forum, Tom Crouch with the aeronautics division at the Smithsonian or Jim Wilson, editor-in-chief of "Dots & Dashes" the official news and information arm of the Morse Telegraph Club.
Hope the above helps,
