it's true. jet trails evaporate fast if i recall from my childhood, when i saw jets flying and looked at their trails they went faster than i liked. and i saw a weird thing one day. there was this trail in the sky but it was falling. i've never seen that. usually they evaporate. and regular jet clouds and chemtrails do not fall. but this line was so weird, it was falling down.
