There are a number of private jet flights out of my nearest airport (London-Luton) every day. I enjoy tracking the flights for a time. Sometimes I Google their registration to see if it's anyone I recognise. Just prior to the 2012 Olympics I noticed one of these flights which appeared to be circling London. With a little investigation I discovered that the plane was owned by a founder of PayPal! Anyone else have similar experiences? Got any tips?
