As a thought on this....in spite of the jogger wearing headphones....what was he going to hear? Engine was out, no prop, oil on windshield...I guess the pilot should have...blown the horn?

As kids, a friend and I used to hang out at a small airport in Palmetto. There was rarely any traffic, unattended, and a great place to go check out some airplanes up close. Keeping in mind this was a time before terrorists were trying to blow up the country, etc....We were out laying on the end of the runway just checking out the sky, and almost got landed on by a biplane crop sprayer. Even with his engines running, AND us looking up to the sky, we did not hear or see him till he was about 20 feet away going over us.
