It's a great pack- I can never land the thing without breaking the struts though, even on stronger gear!
I only get it down 2 out of 5 times myself with the NASA gear and about 4 out of 5 with the stronger gear installed. I usually do not end up with a crash bar either way and end up smokin&sparkin down the runway. I have had to abort just about every challenge flight at least once or twice and water ditch.
It was designed to be a realistic sim adventure as compared to the unrealistic aircraft dynamics most aircraft produce in the sim.
I have gotten quite a few emails from Rockwell, Boeing and Kennedy Space Center all telling me how much they get a kick out of the package since they dont get to play with the toy they designed or get to play in the real shuttle simulators.
