Yeah, Aluminum is shyte, that is why MB uses it for all kind of important parts...also why all our planes are made from that shyte Aluminum.
I always felt these retired air force planes are on display because they are obsolete....you know like the B 52s which are still in the air after what, at least 50 years?
...yeah that Aluminum is shyte structurally, it always fails.
