The bachelor brothers from Scotland had a veritable circus in that old barn. There were steam traction engines that powered threshers and gins they used in the fields. There was a car they built from the engine to the ratty cabriolet top. There were even the discarded remnants of a flying machine hanging from the rafters.
The home built aeroplane was a half-baked attempt to draw some publicity for the saw mill. It had worked like gang busters for Roscoe Turner and Gilmore Oil. Only problem was Roscoe could actually fly. The army had taught him how during World War I. Neither John or William thought about the need for someone to teach them how to operate the machine. They built it and just got in the thing.
The rest, as they say, is history.
