Couple hundred feet. Saw a plane that was taking off collide with one still on the runway. I was just off the taxiway.

Saw another two occurrences of a plane hitting trees due to power loss on takeoff

I was almost in a couple myself. Almost hit a tower cable in a snow storm that rapidly developed, and another where made an emergency landing due to engine failure.

I grew up with several of my dads friends that I had flown with dying. I didn’t end up becoming a pilot as my career.
