Speaking as a fighter pilot, I CANNOT STAND a bug spot on a windscreen. Anhyone who's ever done a break turn for a smudge on the side of the canopy knows what I am talking about...

I buff and polish the windscreen on my GA plane as well, and have a shammy in the hangar at standby. This guy ain't doin' this for SWA...he's doing it because he hates a dirty canopy. I get it...
