I remember being told in Vietnam that the 175 round reached a height of 33,000 ft. at max range. That often crossed my mind while traveling by Huey.

I read about an observation plane pilot over the beach during a landing that had an Iowa class broadside go by him. I got the impression that he was impressed.
They were supposed to call out direction and "max ord" of the shot, which I assumed was the height. I would hear them call most of the time.
Did have one salvo go by quite close, giving the CH-46 a good jostle and pissed off pilots. Apparently was not announced over the radio.
Many years ago when I worked at Aberdeen Proving Ground there was vertical fire testing where the piece would be elevated to 89-90 degrees (or even past 90 depending on the high altitude winds) to allow recovery of the projectile which would impact a 1/2 mile or so away.
Obviously, the FAA would close off air traffic overhead.
It may be apocryphal, but the story was north bound air traffic would be routed east of APG over Delaware while southbound traffic would be west over PA and central MD. In effect, APG was the Jersey wall between these lanes.
