Plane seems to disappear over Kachemak Bay.It was a clear blue sky day. Weds at about 5:45 pm we stepped outside to fly a RC plane out East End Road, outside of Homer, within the first few laps i saw what appeared to be a jet, 5000' +, heading north, & seeing the bottom view of the plane located over Kachemak Bay, noticed no contrail, then noticed the sun gleaming off plane, and noticed it was at different elevation & different heading, saw more like the side of the plane heading more of a NE direction, 1000' more or less, the next second it had vanished! it was like it had stealth ability, we had watched it heading in our direction for about a few minutes, then it was gone! basically right over Kachemak Bay. WTF? Did anyone else happen to see this? If you put your arm out it was about 1/2" in size or so , close enough to see it there, then gone, there was no clouds, nothing to block view of area in sky ! to weird..
