This explains why the ballons on the right side are bigger ten on the left because their gaining mor height, less air pressure and mor size.

Just an idea, it really makes an difference. Weatherballons are planed to explode at great height to drop the sensors. I saw an documentation that explains that Weatherballons are housebig at real big heights. On ground they have 1 meter.

Of course it would - GE isn’t magically detecting the altitude of any feature on the image, it is just using the known height of each location on the earth from the topographical model.

But I am not convinced by James’s insistence that this is definitely a satellite image, regardless of the copyright image. It certainly looks like aerial photography to me - you can see the jump from aerial photo to satellite image between the seventh and eight notch of the zoom slider. This is especially noticeable in the imagery immediately to the north, which seems higher-resolution but is still labelled DigitalGlobe.

Seen here: http://googlesightseeing.com/2006/04/25/frankfurt-plane-shadows/ is four shots of an airliner taking off. Tracking it’s apparent size as it grows closest to the camera, it appears to “grow” fairly quickly as it ascends. Between that and the low-res imagery that blurs the edges of these phenomena I would say balloons are a very likely possibility. Rubber balloons that they launch by the trillions here in the states every f*ck the wildlife day (second and third Thurs. of every month).
