Haven’t tried any famous bridges yet but I’ve noticed twice now that attempting to fly under, what look like, very wide and tall bridges (I’ve tried the new Severn Bridge and some elevated highway in northern Italy…somewhere near the coast in the hilly bit south of Milan) and both times I “Have collided with an object.” But it sure looked to me like I had 10s, if not 100s of feet clearance on all sides…
What gives? Are bridges solid (but see through) objects?
