0.2.1 Atlas Launch History
The data in Table 41 summarize the flight performance of all Atlas and Atlas-boosted
space-vehicle launches since the program began in June 1957. A launch sequence
number is provided in the first column, a mission ID and launch date in columns 2
and 3. The vehicle configuration or Atlas booster number is given in the fourth
column, while the fifth column shows whether the launch took place from the Eastern
or Western Range. The last three columns in the table show, respectively, the response
mode assigned by RTI to any failure or anomalous behavior that occurred, the flight
phase in which it occurred, and whether the vehicle configuration is considered
representative for the purposes of predicting future Atlas reliability. Launches through
sequence number 532 were used in the filtering process to estimate failure rate.
