0018933 separation and parachute deployment were achieved satisfactorily, The nose cone was located after impact by a very strong, steady, directional Signal from the recovery transmitter and by sighting the dye marker, It was completely dry inside and 2 vacuum seal had been maintained for 2-1/2 hours, On the next round, second stage ignition was observed and the range radar showed nose cone separation at approximately ~105,000 feet, The payload descended very rapidly and could not be located by the search craft. The radar plots gave no indication as to the nature of the malfunc- tion which evidently occurred, It is possible that the second stage para- chute failed to deploy or that the first stage parachute was fouled by the ‘motor, These were the final tests carried out in the development of an ocean recovery version of the cloud sampling rocket, The results indicate that the improvements in design made subsequentto the field operation have resulted in a more practical system then the one available in April, 1958, However, further flight testing would be desirable if the rocket is to be used in a future cloud sampling program,
