Mark - nice shots but sorry to say you are not being sprayed. If
you think about it for a sec - what good is spraying if the
substance stays up in the air? These shots show the trails not
disappearing so what ever it is (H2O) is not making it down to your
level.
Contrails (CONdensation TRAILS) are formed by aircraft without a
doubt.In some circumstances the trails just fade away but when
conditions are just right (very cold but moist I think) they can
catylise the rest of the moisture in the sky to condense and form a
thin opaque cloud cover that can last days. If you want any more
info try asking these guys a question in the forums. They also deal
with the states.
