An unmatched experience of Aerial Delight in the ‘Silver Queen’ Stearman. “Silver Queen” is a beautiful Boeing Stearman with a Lycoming R-680 300-horse power 9-cylinder radial engine. We cruise along at about 115 mph, usually around 1200 feet above the surface, the perfect altitude and speed to appreciate the never-ending views you’ll see. Originally built in 1942 as a WW II primary trainer, ‘Silver Queen’ has modified to meet modern safety standards and for additional performance. What Sets Us Apart The year 2024 will be our 9th year of offering Open Cockpit Biplane Rides off the Easton, MD airport (KESN). We have carried well over 1500 passengers, one at a time without incident, a perfect safety record. Seasonal flights begin by May 1.
