I quit watching the history channel when all the good stuff went to the military channel. And then its being weeded out for reality tv trash. I would pay for a "retro" version of the military channel, with some of the shows that were broadcast back in the 80's-90's. I watched many an episode of Firepower and Wings.
And heck, even throw in some declassified testing and documentaries on aircraft and weapons that were made back in the 40's to 70's. Those are very interesting to watch
