I've come that close as well. 4th hole Falmouth (ME) CC from 165. Pin right center, right at the bottom of a ridge. I hit the top of the ridge and gravity worked in my favor. After hanging on the edge of the slope it started to wobble and trickle back down. It always stayed just outside the hole, but settled 6 inches away.
I had another at Spring Meadows in Gray, 16th hole about 110. I threw my gap wedge at the center of the green. I normally hit that around 115, so I played it back and tried to drive one in with some zip on it. I surprised myself when it spun back 10 yards, just missing hitting the flag stick on the way by.
So that makes my longest hole out 85 yards (for eagle), but it was a scramble so I feel like it only half counts.
