Do you know what is contrail?

Contrails or vapor trails are condensation trails and artificial cirrus clouds made by the exhaust of aircraft engines or wingtip vortices which precipitate a stream of tiny ice crystals in moist, frigid upper air.

OK, those are not my words… I got it from Contrail’s Wikipedia.

Why am I talking about contrail?

About two weeks ago, while trying to capture clouds, I saw the contrail… well I did not know what it’s called at that time. I just called it airplane exhaust smoke.

Then, last Thursday, Jonathan saw me downloading my photos from my camera to my notebook. When he saw the ‘contrail’ photo, he said… ‘Wah… contrail.’… I replied ‘WHAT?’… he answered ‘that is contrail’… I asked ‘are you sure that is the right name?’… he said he sure.

Then I google the word ‘contail’… yes I spell it CONTAIL because that’s what I thought it was at that time… That day was the first time I heard the word Contrail.
