¶3Before KOELSCH and TRASK, Circuit Judges and BYRNE,* District Judge.
¶6Marilyn Maynard sustained severe personal injuries when a horse she was riding became frightened by the sonic boom created by a U. S. Air Force SR-71 aircraft and threw her to the ground. Invoking the Federal Tort Claims Act (28 U.S.C. §§ 2671-80), she commenced this suit against the United States to recover damages. The gravamen of her complaint was that the aircraft’s route was negligently selected. The United States moved for summary judgment on the grounds that the negligent act was one within the discretionary function exception to the Tort Claims Act (28 U.S.C. § 2680(a)). The district court granted the motion and dismissed the action. Plaintiff has appealed. We affirm.
¶7The government’s uncontroverted affidavits showed that the decision to conduct operational training flights in the supersonic SR-71 and the order directing such flights was made by General Naz-zaro, Commander of the Strategic Air Command; that the SR-71 aircraft was flying such a mission at the time of the accident; that the actual selection of this particular flight route was made by Lt. Col. Caselton, Chief of the Navigation Section of the 9th Strategic Reconnaissance Wing at Beale Air Force Base, to which the aircraft was assigned; and that Col. Caselton laid out this flight in accordance with the requirements of applicable Air Force Regulations 55-34 and 55-34A.
¶8The Supreme Court, in Dalehite v. United States, 346 U.S. 15, 73 S.Ct. 956, 97 L.Ed. 1427 (1953), declared that the government, under the discretionary function exception to the Tort Claims Act, is immune from liability for injury *1266resulting from decisions made at the planning or policy level, but is liable for injury which results from a negligent act at the operational level. The Court expressly refrained from precisely drawing the line between the two “levels” but nevertheless declared that
“the ‘discretionary function or duty’ that cannot form a basis for suit under the Tort Claims Act includes more than the initiation of programs and activities. It also includes determinations made by executives or administrators in establishing plans, specifications or schedules of operations. Where there is room for policy judgment and decision there is discretion. It necessarily follows that acts of subordinates in carrying out the operations of government in accordance with official directions cannot be actionable.” (pp. 35-36, 73 S.Ct. p. 968) 1
¶9So here, we believe, in agreement with the district court, that Col. Caselton’s selection of the route to be taken by the SR-71 was the act of a subordinate in furtherance of governmental policy and under official direction and hence not actionable.2
