13.3 Deliberate Forced Aircraft Impact
After the terrorist attack in the USA on September 11, 2001 the question arose to
what extent nuclear power plants would withstand an impact of a large commercial
airplane or rather which damage scenarios are to be expected. As a result many
national and international studies were conducted, in which possible scenarios for a
deliberate forced crash were considered and the load functions for the crash of a
large commercial airplane under consideration of the spatial load distribution were
developed. Among others, the author was involved in several of these studies. Since
most of these studies are confidential and therefore not open to the general public,
however, only general references and information can be discussed here.
