Attention: you need 3 mods to use this plane: weapons bay, nuke bomb and as last but not least the sound barrier mod. Ac. 1 Weapons bay opens itself Ac. 2 not really important cause it's just the detacher it's just important for dropping the bomb Ac. 3 the parachute for landing As bomb-friend you should download the advanced target mod. thx 4 download and have fun
