Yip.
I have been there. Enjoyed it unfortunately temperature was about -5'c and it was windy so it was COLD.
Some of the settings where quite spectacular like the LH B747 "Classic" mounted high above the grounds, guess the bottom of the rear fuselage sits at about 100ft or so? Not only do they have all things aviation, but lots of naval stuff ( few submarines) cars and steam locomotives like I had never seen before. A beaurifully restored ME109 crowned the whole show.
It was definately worth a visit. There is another related exhibition that boasts both TU144 and Concorde jets side by side for an easy comparison. Worth while as visit as well.
