Has anyone found Training Mission 7 to be easy? This is where you have to bring down zepplin while also defending your base.

Also, just how many missions are there? Until today, I thought there were only 3.

their are 7 total, and none involving carrier

seven is easy once you figure out that the enemy plane come in groups of two, once you shoot down the first two, its best to take a few shots at the zepp (which you dont have to shoot at the engines first like in the zepp mission but can shoot at the body as a whole), and then return to base to get the other two. Its pretty easy once you figure out practice enemy planes suck in a turn fight with a human

Thanks Kptn. I did find out that you can't waste much time or that zepplin will be over base and it's all over! It sure takes a LOT of bullets to kill that thing. Oh yes, it is most surprising that there is no carrier mission.

The carrier was added in 2011 the game with the missions were created in like 2008 or something. He just added a few levels here and there.
