Questione giuridica chiave
Whether the July 15, 2001 knee incident qualified as an accident under the applicable pre-ATSG law.
Decisione estratta
The incident had to be treated as an accident because the misstep, reflexive uncontrolled jump, and landing formed one coordinated sequence interrupted by a program-wrong movement.
Motivazione estratta
The court refused to isolate only the landing phase. The whole movement was uncoordinated and reflexive, so an unusual external factor was present.
