Notes:My aircraft is a 1971 PA28-180, tail number N1995T. The winds aloft forecast for West Georgia were in excess of 90 knots at 14,000 ft MSL. As I climbed through 11,000 into the wind, my GPS showed my ground track was backwards. I briefly leveled off and observed a tailwind of 95 knots and a ground speed in level flight of 210 knots. I then climbed to just under 14,000 ft and turned for optimum tailwinds and saw a ground speed of 205 knots in level flight at that altitude. I then put the airplane into a descent and recorded a peak ground speed of 260 knots as I passed through 11,500 ft. This was observed and video recorded on my Garmin GNX375, my Garmin G5, and ForeFlight on my iPad. I uploaded the video of my flight on YouTube at the following link: https://youtu.be/g4P6k-h-bi0

Notes:Winds Aloft Forecast for KBIL at 12,000 270@79kts.
The first picture is of an FAA radar replay courtesy of my friends at the tower/approach control. The radar updates at 6 second intervals, so it captured a higher GS than FlightRadar24 which saves data in 10 second intervals. The highest GS I saw in the aircraft was 300mph (261kt) but I have no evidence for this.

Notes:The attached pictures are from a trip I took to Oshkosh in 2002 in my 1965 PA28-180, Cherokee 180C. We were flying over South Dakota and had some pretty good tailwinds. How often do you see a Cherokee go 225 MPH?
The second picture was returning to Oregon, over Cheyenne Wyoming - talk about headwinds! 33 MPH - I could have gone faster on a scooter!
