PH-KCH (cn 48562) When it comes to spotter-friendly airports, Amsterdam has one of the best. With a huge rooftop observation deck and a snack bar, its no wonder so many aviation buffs consider this airport a must-see. Here we see KLM's PH-KCH parked at the gate in its old colors, and with a bevy of other widebodies visible as well. September 11, 2003
