Still do not know why some did use this model on the airfields, but I still think these massive Vander water tower models, do not belong at the airfields edge. Prefer to see Water towers as a model at the edge of the towns.
I did found my old mod that exchanged these Vander Water towers by wooden observation towers (whats in a name). The used skin was a part from other sources and made by talented skinners, so not by me. I only collected them in to a file so it can be used in the JSGME tool mod folder.
Unlike most other models this can be used, (if an water tower does show up), in every off line mission or PW-CG, because it simply exchange the ingame Vander watertower skin.
Panthercules maybe this is also interesting for your download page, feel free to use it.
Edit: correcting career does not use water-towers and make the text more clear.
