For the second time in 4 months, a DHC-6 Twin Otter stopped at OQN (Brandywine) on the way home from a surveying mission in Africa. It dropped of an employee who lives in West Chester, PA. N181CS, a 1968 DHC-6-200, arrived around 1:30pm after a 4 hour flight from BGR (Bangor, ME). But that was one of the shortest legs of its journey home. N181CS started in Kenya, where it had spent the last few months doing aerial surveys for oil. They left on Feb. 18 from The Netherlands and routed through Scotland, Iceland, Greenland, Frobisher Bay, Canada (where bad where kept them grounded for a day), Bangor, ME, OQN and finally to 00NC (N.Raleigh, NC). One of the pilots told me it was great to land at a "real" airport where it was warm. She said it was 75 degrees colder in Frobisher Bay! The long boom on the nose and the wingtip pods are part of the sensor system that detects magnetic anomalies in the Earth that indicate oil. The aircraft is headed for maintenance, where the boom will be relocated to the rear. After refueling, N181CS departed runway 27 for the flight to North Carolina. The company that operates the aircraft has 3 others (including N162DE that came to OQN in October '13). See the N181CS folder for the photos.
