[Effect of hot-air balloon crossings on animals in the open air]

Since the middle of the eighties owners of animals increasingly claimed compensation from balloon pilots. They asserted, that their animals got restless due to strange optical and acoustical stimuli caused by low altitude crossing of hot-air balloons and were damaged while trying to get out of the way or to escape. Very low altitude "Contour crossing" of hot-air balloons, mainly forming the basis of complaints, is only left possible in a limited degree in Germany since the air traffic regulations were changed to a higher minimum safety altitude (Air Traffic Act, LuftVO, version of March 21, 1995) and the violating balloon pilot may be disciplined. The paper is dealing with the principle of hot-air ballooning, with the feasibility of the pilot to avoid and restrict damages, with the possibilities to assign damages to a potential cause and with the legal basis.
