But they would heat the water up and introduce small amounts of air into the water, right? And since cameras can see infrared a lot better that we
can, could it be possible that that camera is picking up some sort of heat reading that is higher than the surrounding water?
If so, then seeing ship tracks is possible.
Because the air over the sea is much stiller than that over land (because of much less temperature variation) the tracks last for much longer and can
string out for miles and miles.
People really should read links before shooting their mouths! Do you believe after reading the wikipedia article denythestatusquo?
The big difference between a ship track and a contrail is that one tends to form clouds of water droplets, while the other tends to form clouds of ice
crystals.
Niether one is a "chemtrail" in the conspiracy meaning of the term.
