Andy Parks stands inside his Vintage Aero Flight Museum at 7125 Parks Lane, east of Fort Lupton at the Platte Valley Airpark, which holds a world-class collection of World War I-era uniforms, memorabilia and replica aircraft that he builds and flies.

An impressive collection of flight-worthy replica aircraft and historic memorabilia are hidden inside the Vintage Aero Flying Museum in a colony of nondescript airplane hangars at Platte Valley Airpark.

Such planes and aviation history are rarely found all in one place, let alone at a tiny airport in Fort Lupton. Outside, small planes pass by on the thin runway, the buzz of propellers fading in and out.
