I've seen some contrails, when the plane was coming right at me, that appeared to be going straight up. There is no way that they could have been, but that's how they looked. It can really throw you off if you aren't used to it.
For those having trouble uploading the PDF, search "Case Orange - Belfort Group Report on Contrail Science"

Can you give a reason why they are chemtrails and not contrails?
