$this->bbcode_second_pass_quote('SD_Scott', 'T')he weather report stated that we had a big high pressure system in the area. Is the flight traffic across the US low right now?
Doubtful SD, traffic may be very slightly less, but the reality is that at high altitude the conditions may just not be favorable for contrail formation, thats all. There are delays in the NE but not significant enough to cause what your seeing.
You just dont get contrails all the time.
