Guetersloh certainly had a railway, and I seem to remember cattle on the airfield, but not sheep. If not within the perimeter, then certainly only just outside. We could see them from Met., which was at the base of the control tower/ wing ops.
During a spectacular thunderstorm, a lightning strike earthed in a bunch of cows ............ as to injuries, I know not, but the event was recorded for posterity in the Obs Book.
Amost every sort of weather phenomenon could be recorded within the coding system, but "cattle struck by lightning in the vicinity" defied attempts to encode it.
