A brief History of Bonanzas to Oshkosh
Each year in late July about 100 Beechcraft Bonanzas and Barons assemble in La Crosse, WI and fly in the world's largest formation of civilian aircraft, to the world's greatest celebration of aviation at EAA AirVenture, in Oshkosh, Wisconsin.
Bonanzas to Oshkosh began in 1990 when Wayne Collins and a few friends decided the only way to ensure camping together was to arrive together in formation.
For a review of our history, how it began and evolved, see the B2OSH History page. The early history is posted with Annual Reviews and articles dating back to 2001.
Wayne Collins led Bonanzas to Oshkosh until 2001 when Elliott Schiffman took over the reins. During Elliott's tenure B2OSH established a nation-wide network of regional training sessions. Organized practices led to ever improving B2OSH flights and added a wonderful layer to the social fabric. In 2007 Larry Gaines slid into the left seat.

Why Bonanzas to Oshkosh
Today our focus remains firmly fixed: pilots flying the best general aviation airplane camping together in friendship and camaraderie. The formation arrival is our means of accomplishment.
Our requirements are B2OSH membership and signup on this website, demonstration of basic formation competence in the previous 6 months. We encourage you to maintain your membership in ABS and EAA to reduce your B2OSH Oshkosh costs.
We cannot stress too strongly that this event focuses on friendship, camaraderie and a grass-roots structure. Especially if you are a first timer, do not hesitate to walk up to any cluster of pilots and friends, introduce yourself and join in. This is how friendships are made. We all have a common interest. If you are at all hesitant, pick out a Staff member (bigger name badge) and he or she will introduce you around.
The camaraderie of the Bonanzas to Oshkosh crowd has led to other same-type mass arrivals. B2OSH supports the efforts of the Mooney Caravan, Cessnas to Oshkosh, and Cherokees to Oshkosh, making the North 40 a truly special place to be in late July each year.
