Space Shuttle Data
==================
This dataset gives information about the 23 space shuttle flights
before the Challenger disaster. We know the temperature of the time
of the flight and whether at least one primary O-ring suffered
thermal distress.

Ft   = flight no.
Temp = temperature
TD   = thermal distress (1 = yes, 0 = no)

Data based on Table 1 in J. Amer. Statist. Assoc, 84: 945-957, (1989),
by S. R. Dalal, E. B. Fowlkes, and B. Hoadley.
