What you saw could have been a satellite or the Space Station. The space station is sometimes the brightest object in the sky. Most satellites pass
through the sky at about the "apparent speed" (the speed as it appears to an observer on the ground) of a plane. We can see these satellites
because they reflect sunlight. It can be sunny high up in orbit, even when it is dark on the ground.
One interesting type of satellite are the "Iridium" satellites, which can be very reflective. Iridium satellites are know to "flare up" (reflect
a lot more sunlight) for 30 seconds or so, and be very bright for that time, before its reflected sunlight fades away into almost nothing. These are
called "Iridium Flares".
Here's a good website that can tell you about satellite sightings in your specific area...
...I don't know where exactly in Germany you live, but it seems from this website that the Space Station was not
visible in Germany last
night. However, there were Iridium Flares last night, depending on what location in Germany that you plug into this website.
As for whether all planes blink or not, all planes do have blinking navigation lights, but there are some lights on a plane that are turned on when a
plane is on approach to an airport that are very bright (either white, or sometimes more amber color) and do not blink. These landing lights are so
bright, that they "drown out" the blinking lights to the point that the blinking lights cannot be seen. You don't need to live right by an airport
to see landing lights. These lights are turned on sometimes 50 miles or more from the airport.
