from any airport.
Second, you must have permission from the landowner to launch.

It helps to launch from public ground like publically accessible
field paths, because there you only have to ask the next available
representative of the public, who is usually yourself. ;-)
The 1m zone on either side of small streets connecting small villages
is usually considered a public area. If there is no traffic and
enough room to park your car, then you can set up your launch equipment
there too. But take care not to irritate occasional bypassers!
Third, you have to stay underneath the surveyed airspace with your T1 powered
rockets. Usually it begins at 300m AGL but that varies from place to place.
In Germany there are many "Tieffluggebiete" (low flying areas) used by the
military who don't like "missiles" crossing their flight path! Check with
your local "Flugsicherungsdienst" (the German FAA) if in doubt. A good
idea is to buy a 'Luftkarten' of the area in question and check
If you chose to fly T2 powered birds, you ALWAYS need a "Luftraumfreigabe"
(waiver), no matter how high your rocket is going to fly!
