Still cleaner than a Delta plane.
No kidding! I get worried if I don't see fifteen gallons of hydraulic fluid streaking out of the wheel well all the way to the APU. They should have painted the bottom of the planes a nice grime color.
It's always easy to spot a European or Asian carrier. The belly of the jet is clean....:bandit:
Lol, RVSM what's that? One day I wish I can fly above the weather.
