FSX RAF Tornado Coningsby 1990 Alpha Fix. This patch removes all alpha channels used for masking tanks and rockets for Daryl Payne's ADV RAF Coningsby 1990 package. Alpha channel masking leads to strange side effects in FSX. If you are troubled by these side effects in my FSX replacement package please use this patch. Make a backup of the original textures in case you like to revert. By Martin Gossmann - The Owl's Nest.
