Proschan (1963) reported on the times between failures of the air-conditioning
equipment in 10 Boeing 720 aircraft. The aircondit data frame contains
the intervals for the ninth aircraft while aircondit7 contains those for the
seventh aircraft.
Both data frames have just one column. Note that the data have been sorted
into increasing order.
