I wanted to share this hilarious experience with you: if you have a mobile GPS system, possibly in your phone or your PDA, try using it on the next plane you fly. Forget about "electronic devices may interfere with on-board equipment" or similar warnings, and enjoy the unobstructed view to the sky with its GPS satellites. As you can see in the picture I used my mobile GPS with Bluetooth. It was only later that I learned the guy in the seat next to me was actually an Airbus engineer warning me about interference. We both stared amazed at the display that read about 600mph or 900kmh. Never been faster in London city traffic!
