ROCKET INFORMATION

    Unfueled rocket weight: 9548 lb
    Gross weight at takeoff:: 29,013 lb

ROCKET PERFORMANCE

    Program angle: Seven degrees
    Time to burnout: 67 sec
    Velocity at burnout: 4985 ft/sec
    Altitude at burnout: 23.5 miles
    Time to zenith: 228 sec
    Altitude at zenith: 99 miles
    Time to tail blowoff: 408 sec (explosion)
    Altitude at tail blowoff: 6.2 miles
    Flight duration: 420 sec approximately
    Impact coordinates: 48 mi. north

BALLISTIC DATA

    Theodolites: Mitchell - Tracked down to ground haze; Askania - satisfactory
        operation
    Cameras: Bowen-Knapp - Satisfactory operations
    Telescopes: One station tracked 60 sec, other 72 sec. Test station tracked through-
        out flight.
    Radar: Both radars tracked until 408 sec. Good data records obtained
    Doppler: Good signals until after burnout, then considerable interference from
        ionosphere experiment. Data tabulated from 0 10 126 sec, poor after 116 sec.

DATA RECOVERY

    Physical recovery: The warhead separation explosives did not operate

COMMENTS

    Rocket performance: Two-rpm roll rate after burnout. Rocket oscillated during
        descent. Radio blowoff signal given at 310 sec, timer signal at 325 sec. War-
        head did not separate until rocket disintegrated from violent explosion at 408
        sec. yaw less than five degrees during burning. Good propulsion performance.
