Hello,
I've been playing Minecraft for a while, and the modifyability of the game struck me immediately.  I looked at their forum: there was an entire section devoted to it!  I poked around a while, and I found something that many of you would enjoy.  It's a modification that introduces WWII aircraft into the game with support for mouse control!
Don't like flying?  Fear not, there is another mod by the same man- the World War II Vehicles mod.  It has a tiger, a sherman, a Willys Jeep, a Kubelwagon, a 37mm flak gun, and a quad 20mm flak gun.  If you want to pack some firepower in the event of a crash, there is another mod for WWII guns!  Springfields, Enfields, Mausers, Lugers, they've got them all!
It's a great way to introduce your kids into the art of flight as well.  I certainly had fun with it.
