Re my posting yesterday. Ted has come up with a revised mast that can be seen, just, at up to 10 miles away. Well, it can if it's on the skyline. The trade off is that it looks far less elegant close up. But if you're close to a mast I guess aesthetics come second to a change of underwear!
Place the .bgl file in your FSX's Addon Scenery / Static Objects Library's SCENERY folder, allowing it to overwrite the existing file
