+
+UAV HADR Mission
+
+The following model specifies the ingress phase of the UAS HADR 
+reference mission. The ingress phase is preceded by the preflight 
+phase, and followed by the on-station phase.
+
+This model contains an unexpected behavior in which the UAV status
+is acceptable but the operator aborts the ingress (trace 2).
