Delta Airlines

I just used mine on a flight from Minneapolis to Atlanta. I know there was a tail wind of some speed but we left 50 minutes late and landed 15 minutes after the scheduled arrival time.

I did have my GPS going and saw a an average speed of 560 MPH and a top speed if 578 MPH pretty cool.

I did use the screen shot function and downloaded the photos to the computer for a memory.

It was neat to see where we were traveling, I did on occasion zoom in to .5 mile and she kept up with the screen update but the 5 mile setting was best.
