Groundspeed	227 kts
Notes	As shown by the GPS, I was right over Manchester, NH. I was doing some climb and altitude tests on my Tiger. Passing 15,000 feet I noticed I was flying backwards while climbing. I played around a bit and succeed in seeing a 1 knot groundspeed. Unfortunately, it was hard to hold the precise attitude necessary and I never got a picture of that. Then I turned around, decended to 13,500 feet, leveled off and hunted around a bit to find where my ground track and compass matched up. I took several pictures of the GPS. Most didn't turn out because it was after sunset. When I tried the flash, the reflection off the glass made it impossible to read.
