today around 1415 february 5 a friend and i were having a discussion and she observed the craft with two contrails behind it and remarked at the steep angle that it appeared to be taking. we both assumed it was a jet at high altitude. we looked away for a couple of minutes and when we looked back, both the craft and the con trails were gone. it was a very clear sky and we saw no evidence of con trails or planes. both of us very surprised and a bit disturbed as neither of us had a good explanation.
