     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.

_F_o_r_m_a_t:

     The data frames contain the following column:

     `_h_o_u_r_s' The time interval in hours between successive failures of
          the air-conditioning equipment

     The data were taken from
