The Criminal Law Amendment (11)(draft) intends to add parabolic behavior at high altitude to the type of criminal act of "endangering public safety by dangerous method". The core of judicial determination of crime of endangering public safety by dangerous method lies in judging whether parabolic behavior at high altitude has two core elements:dangerous method and endangering public safety. Through the typological analysis of parabolic behavior at high altitude, it is found that the existing legal means are sufficient to regulate the behavior, and the criminal legislation should be modest and not regulated by new provisions.
