Draconian welcome to GE. Does not look like this has been posted before. I will include this on the next collection of planes in flight from aerial photographs. Your other post which is an MD11 approaching Honolulu has been posted previously. This is also an aerial photograph and not a satellite image.
All the satellite images have a copyright bottom of screen DigitalGlobe or EarthSat
Have fun

Not sure if this one has been found yet.
A pretty clear example of the satellite double exposure artifact. Interesting how the plane is white where the exposures overlap, gray/tan on the panchromatic image, and with trailing red streaks on the blue multispectral image.
Just read more than I could quite understand on satellite scanning tech, "time delay integration", "pan sharpening", and so on. Pretty amazing, and complex..

If you read enough to find those tems, look a little further for orthorectification and you will have just about the full glossary of the behind the scenes work in Google Earth's data production process for images. Of course, there is also work in the terrain, data layers, and 3D buildings processes as well. The goal, though, is that all of this is invisible to end-users who just type in an address and enjoy the fact that it all works as expected. ;-)

pfly you are correct an unposted Airbus A300-600 to add to the collection.
Most of the technical data about satellites make is not unfortunately written in a manner that is easily understood. It often sounds more complex than it really is.
In the old days of black and white photography it was a Manufacturer goal to make a film that was equally sensitive to all colors. This goal was never really achieved. Electronic imaging gets closer because any imbalance in sensitivities can be digitally processed out. A panchromatic image would be the ideal black to white image supporting all of the subtleties of a true gray scale. In the satellite image reconstruction, which assumes a stationary image, white is equivalent to equal amounts of red, green and blue. When you superimpose the displaced image the color and black and white image processing is making wrong assumptions about both the foregound and background actual colors.

Ack, don't say orthorectification! :-) The org where I work is just now working with a vendor to get a new set of orthos, this time using LIDAR data in the post-processing. Between difficulties with the LIDAR and delays in flying due to clouds, it is all several months behind schedule. For a short while when I first began here I was doing quality control on incoming orthos. Thankfully, now I just get to watch the trainwreck from a distance.
The details of satellite-made imagery are pretty new to me. I'm used to seeing airplane/film errors.. even things like bits of lint on the film. Now I have to learn a whole new set of ways for things to go wrong!
As an application, Google Earth keep surprising me in how well it works; but sometimes what seems really novel is the global community of people talking about geography and remote sensing. After years of hearing about the sad state of geographic education, who knew all it takes is a fun tool and a way for people to talk to each other?

Ciao 
Thanks to database update, I found a Fokker 100 likely just leaving Palermo LICJ-PMO from rnwy 20. This airport is not really loved by some pilots because of not easy manoeuvres to take off/land, windshear and the presence of the (too) close Pecoraro Mountain (910 meters high).
Bye

Here's one i found while looking at the new hi-res images of Mumbai, India.
I think it's a 747.
Edit: This one has been added to the "Satellite captured Planes in flight" database, so i've removed my placemark.

Here's another one this time over Fukuoka, Japan.
Could be a MD-80.
