        Cameras: Two ballistic, three Bowen-Knapp, one spectro camera at T1, and
            two metro cameras
        Telescopes: Four stations
        Radar: Two SCEL 584 S-band units

    Airborne
        Radio Cutoff: AN/ARW-37 radio receiver

ROCKET INFORMATION

    Unfueled rocket weight: 8741 lb
    Gross weight at takeoff:: 28,106 lb

ROCKET PERFORMANCE

    Program angle: Seven degrees north from vertical
    Time to burnout: 65.3 sec
    Velocity at burnout: 4000 ft/sec
    Altitude at burnout: 22.4 miles
    Time to zenith: 191 sec
    Altitude at zenith: 67.4 miles
    Time to tail blowoff: 288.7 sec
    Altitude at tail blowoff: 39.8 miles
    Flight duration: 551 sec (main body)
    Impact coordinates: main body - north 26.3 mi., east 10.8 mi., nose section - north
        29.4 mi., east 10.4 mi.

BALLISTIC DATA

    Theodolites: Satisfactory operation, some Askania stations tracked rocket to impact
    Cameras: Satisfactory operation
    Telescopes: Satisfactory operation
    Radar: Beacon was fair and tracking was in automatic for about half of flight

DATA RECOVERY

    Telemeter: Normal operation until warhead blowoff
    Physical recovery: Warhead separation was effective. All items for which recovery
        was desired were recovered in excellent condition

EXPERIMENTAL DATA

    Smoke trail experiment: A photographic record of the smoke was obtained from 67
        sec until 89.2 sec. Indications are that the experiment was a distinct success.
    Shadowgraph experiment: Film casette was recovered in excellent condition

COMMENTS

    Rocket performance: Flight was normal to 22 sec at which time the rocket began to
        rock and pitch. Failure of vane III at 22 sec caused the erratic flight. The
        cause of the vane failure ws not determined.
