LMAO. SOmeone cried to the mods about me and "excessive quoting". wtf? lol. does the truth piss you off?

And just how ecactly do you know that they weren't ordinary contrails? did you test them?

Specifically, their study showed that ice supersaturation occurred about 31% of the time in cirrus clouds, confirming existing assumptions regarding the frequency of homogenous (non-aerosol related) cirrus formation. However, they also found that ice supersaturation often occurred at temperatures warmer than -40C, when heterogeneous (aerosol-related) cirrus formation typically occurs.
Recent measurements made near the tropical tropopause during the NASA Cirrus Regional Study of Tropical Anvils and Cirrus Layers - Florida Area Cirrus Experiment (CRYSTAL-FACE) indicate persistent ice saturation ratios (s i ) of about 1.2–1.3 in cold ice clouds (T < 200 K) even when the ice surface area is substantial [ Gao et al., 2004 ].
We find that ice supersaturation occurs 31% of the time in over 300,000 data points. We also examine the distribution of ice supersaturation with height and find that in the uppermost portion of a cloud layer, the air is ice supersaturated 43% of the time.
