I am a pilot, and I think it is behaviuor like this, that gives this fairly small industry a rotten name! The pilot was stupid, and did something that was totally unneccesary, things like that should be unheard and unseen and not done.
If it was a military pilot, doing tactical training or a mission, OK, but no civilian ever have a good enough excuse to fly under bridges or cablespans.
The stuck wing feller said he flew under to avoid seagulls? HORSEMANURE!!!
There is no justification, and stupidity should not be revarded simply and kindly, but rather extremely harsh, to show where the law stands.
I agree that there would probably have been little or no damage to the bridge, but that is beside the point! The point is that is was illegal, therefore stupid, therefore unneccesary!!!
