Quibble and try to split hairs to your heart's content, but if your sUAS is in a collision with a manned aircraft, we're all screwed. The press will scream like mashed cats and everyone who was on our side in the FAA will run for cover amidst shouts of 'Ah-ha! See we told you so!'. Please, I'd like to keep flying my planes a few more years. Take up model boats or trains till you get your altitude attitude fixed.
