Off to London and Zurich

These are contrails over our house and they are "condensation trails" from the water vapor coming out the engines of high flying jet aircraft.  So of course many of us look up with a feeling of wanderlust, and wondering where airplanes like this might be going.  Well, now there is a simple answer.  It is an App (of course) for our cellphones.  It is called "Flight Radar 24" and you can get it for free.  I will leave out the technical stuff, like it receives  ADS-B transmissions from aircraft, showing where they are going, what their altitude is and how fast they are flying.  All on our phones

So there are two contrails over our house in the photograph.  I watched the first airplane fly over and looked it up on Flight Radar 24, and then when I saw the second airplane fly over I looked that up.  So here are the displays for both aircraft.  They are both flying at 33,000 feet and doing about 560 MPH.  If you look closely you can see the type of aircraft, one a 777 and the other 787 and you can even see what time they will arrive at their destinations!  What an amazing thing it is these days to be able to see where airplanes are going!
