Chicago - O'Hare International (ORD / KORD) USA - Illinois, May 13, 2010
N171UA (cn 24322/733) Smoke on! Powerful and smoky departure by this 747 as it takes off on a long flight to Hong Kong. In the back you can see a BA 777 about to touchdown and much farther behind it the faint lights of an A-320. Meanwhile some aircraft are waiting to line up.
