Arts and crafts lead to an emergency turnaround
Level at 33,000ft... a strong odor similar to paint thinner was detected by both pilots. Cockpit crew initiated a fume checklist. After securing mask and goggles, cockpit crew established communications with flight attendants. The number one flight attendant reported that he also smelled a strong odor and a flight attendant in the aft of the aircraft also reported an odor. Since we were not able to determine the source of the strong odor, and considering that all of the flight crew reported noticing the smell, the flight crew determined that an emergency should be declared, followed by a divert to another airport.
After declaring the emergency, ATC [Air Traffic Control] cleared the flight to turn 180-degrees. As the aircraft was in the turn, the number one flight attendant called the cockpit and informed the crew that the source of the fume-like odor was identified. Apparently, two children sitting in first class had just begun to color with ink markers.
Right runway, wrong airport
A pilot was cleared for a visual approach to Runway 18 and was told to follow traffic. The pilot said that he had the traffic in sight and would follow the traffic. He then descended and landed on Runway 18 at an airport six miles north. When the pilot called (radar approach control), he was asked what happened. He advised that when he turned behind the traffic to follow, he was lined up perfectly for Runway 18 at the other airport, got focused on the runway, and just landed there.
