Narrative:

From the ground I witnessed two airplanes on final to doylestown airport have a near miss as they simultaneously turned to final. The lower aircraft was a high wing and the plane immediately above it was a low wing. I had previously held a student license and estimated they were approximately 500 ft AGL. The [high wing aircraft] took evasive action turning west while the overhead plane continued to final. I estimated the distance between the two aircraft to be about 40 ft.
