Welcome to Germany, where we have Military installations designated as "Militärischer Sperrbezirk" (MSB), that are closed to the public. For example, a shooting range or training ground is such a MSB, as are many other installations or parts of bases. The fact that they are MSB means, that entering them is illegal as a Misdemeanor under OWiG § 114. But every MSB is, by virtue of being a military installation, also automatically surrounded by 100 meters of No-Fly-Zone for drones based on LuftVO §21h. Atop that, StGB § 109G bans photography of military installations, and that is just the tip of the iceberg...
Now, Hapless Alice is traveling the countryside and stops with her Van at the Steinhuder Meer, a lake close to Hannover. Letting her drone with camera fly, she ends up flying it over one of the runways of the Wunstorf Military Air Base, filming the travel and some planes that are taxiing. However, Alice is unlucky and as she gathers her drone, she is greeted by a few friendly Military policemen, who take her drone, her cellphone, and her into custody.
What is the maximum punishment Alice can get jailed for?
