Couple missions I cooked up: Trainz and Phoney War 1940.
Trainz has 6 trains running for up to 45 minutes around England.
Phoney War 1940 has a little bit of everything in a ground based scenario. Units and placement are pure fiction. Big clouds are built in with FMB. Good test of your CEM skills if you fly Blenheim (player is last to take off). If you have startup and warmup down well you'll be enjoying the fireworks as you take off. IF you select Spitfire flight it shows "Empty" for loadout in A/C selection screen, but dont worry, it has ammo.
Made with excellent latest beta patch, ver. 1.00.14305
