I did find this paper linked to below. It states that for persistant contrails to occur a RHi of 100% isr equired and contrails that disappear in seconds are formed in dry conditions.So,again we have a video that appears to suggest that both a dry atmosphere and and atmpshere of 100% humidy are coex...

I think we can only specualte at best that these are 2 different jets at two different heights.It is not possible to tell from the video.I find it almost incredulous tho that 2, so completetly different humidic atmospheric conditions are exisitng in what seems to be relatively close proximity to cre...

As the video illustrates and as I witnessED ,this is not really an issue about lenght of trail but rather why some hang about all day and form gauzy clouds and others vanish within seconds.These are ,after all ,supposed to be simple ice crystals? Also what I witnessed started early morning and ended...

Lads,Ive begun a new thread as the other has descended into farce. I do feel this is a potentially genuine and serious issue. I've spent a couple of days watching the skies and doing research.I may have found something of significance at one of Dublins smaller airports but I shall say nothing for no...

I did see one very low flying craft yesterday but it wasn't emmiting anything.I would describe it as a sort of a sqaut looking plane with 4 engines or fuel tanks.It was a jet not a prop and smaller than a passenger plane but still big n chunky looking...colouring was white.

So...what the photos don't show is the amount of time these trails hung around.All day really and the mass of them eventually formed the milky Haze that didn't start to break till about 11pm. PS.Just tested my Binoculars on a passenger jet.The work like a dream and if I see one of these chemtrail je...

Nano light is going to post some of my pics from yesterday.Sadly photos don't give a sense of the scale of a thing but one or 2 may raise a brow.

The X's or criss-crosses in the sky over Dublin yesterday where much clearer and distinct than appears in that video. His discription of a "checker-board" was apt for yesterday. Ken did you get any photo's of X's above the sky near Blackrock yesterday morning (which where still there 'til...

Quite an interesting panel debate on the matter

Thanks Vanman. I appreciate everyones imput. A lot of the photos I took yesterday contain dense areas of cumulus cloud,not cirrus.I would be happy to upload photos if I could figure out how to attach em to these posts.Anybody? Can cirrus and cumulus clouds occupy the same air space at the same time?...

I read the link you added. It states "...Most contrails last on the order of seconds to a few minutes and only a small minority will last for hours..." I'm not taking about a small minority of trails hanging about for a couple of hours.I'm referiing to the the entire visiible sky covered i...

Are you saying then that is normal for contrails to coalesce into vast swathes of haze that linger for the entire day over most of the visible sky? Its also worth noting that I also observed several "regular" contrails over the same period that vanished within minutes and certainly didnt p...

Hi,how do I attach photos? Cant see an option for this... I can tell you that what I saw yesterday was not BS.I observed this phenomenon till after 10 pm last night.As mentioned this activity has been raised in the Halls of officialdom in the States. Check out this article from the London Gaurdian. ...
