    Today evening when I came out of office by around 7:15 pm, I saw a trail of smoke made by a jet. I was watching the line as it was slowly getting thin due to wind. Then all of a sudden I could see a white object crossing the smoke trail at a high altitude compared to the trail. I could notice it due to a shine from the sunlight & since the sky was clear. I am not sure if it is a plane/satellite/ISS. It was not static & moving at a good speed. In the limited knowledge I have about airplanes, i think the max height they travel is 30k feet when it makes the smoke trail. but this object was high above that.

    they can make the 'trail' higher. also the first jet could have been at 20k and the second, while being higher, wasn't higher than 30k...

    just my 2 cents

    B-52's had a max ceiling of 50,000 ft. This plane was made in the mid 50's all the way to early 60's

    747's can cruise at altitudes above 40,000.

    Yes.. i think it's a plane. Someday I have to see ISS. I have read in the news sometime that it will be visible to the naked eye on specific dates when it is near to the earth.

    I dont think so....If it was a UFO, I would expect it to show some more unique features like random lights/coming down or going up vertically at great speeds. If I had seen even slightest of strange features, I would have run back into my office :D.I dont want those aliens to pick me up for scientific testing:D

    Those trails aren't smoke, they're water vapor condensing out of the engine exhaust. The reason one plane made a visible trail and another didn't is because of different temperatures and humidity levels at those altitudes. This is also why some contrails dissipate very quickly while some last a very long time, and sometimes you can even watch as the trail is only intermittent as the plane flies through varying conditions. I highly doubt you could see even the ISS during the daytime...

    Yes I dont think ISS can be viewed during day.I think it would be visible in the night as a slightly bigger object than the stars or planets..

    Maybe ISS will look a little bigger through the telescope.I watched the super moon through my 50 mm telescope.Struggled a lot to get the focus but in the end got a good view of it.

    Yeah, I've seen plenty of satellites when I was in areas with no significant light pollution. They just look like fast moving stars. :p The ISS just looks brighter than the rest. With a decent telescope you should be able to see some pretty cool detail. Space StationConstruction Visible Through Backyard Telescopes - NASA Science
