Question

What is the longest par 4 ever to be holed out in one in the modern game?

Answer 1

Happy Gilmore at the Waterbury Open LOL!

Answer 2

The official world's longest hole-in-one occurred on October 07 1965 when on the 447 yard 10th hole of the Miracle Hills CG Robert Mitera blasted a 447 yard drive which happed to be the exact length of the hole.  This was then and still is a Par 4

Answer 3

I believe the first answer is correct as to who and when.  If my memory serves me correctly the hole was a dog-leg left and the golfer drew the ball over the corner where the fairway sloped down to the green. A fantastic shot !!
