EXPERIMENTAL DATA

    Solar radiation: No usable data obtained
    X-radiation: No usable data obtained
    Pressure-temperature: Good data obtained on all ram-jet diffuser pressures; data
        duplicates that of V-2 No. 44

COMMENTS

    Rocket modifications: Ram-jet diffuser replaced standard warhead
    Rocket performance: Performance normal up to premature cutoff
    Experiments: Solar and x-radiation experiments failed to produce data due to low
        rocket altitude
