There is a fellow I know that is concerned about contrails that jets leave in the sky as they hurtle to their destinations. I have stepped inside from the patio and brought up the the Flight Aware web site that allows you to see where a flight is going. I just bring up the Pease Tradeport and look at the local traffic. I did this on Sunday June 1st as we had just had an email exchange about contrails and I was assuring the fellow that it’s just water vapor. A jet was streaking overhead at max altitude so I popped in to check it and was perplexed by a fight plan deviation. I had never seen such a thing. It was an Aeroflot flight headed to Cuba. I am just posting this for its mystery. The Aeroflot jet made a rather odd turn from it’s planned route ducked up to Greenland, to a point that is all ice, then headed back South.
