- I recall an estimate of 50 flights by a NASA spokesman. This may be a
- realistic estimate, or it might be optimistic, it is unlikely to be a
- pessimistic estimate. This number is consistent with the statement that
- the last shuttle flight will occur in 2007. This statment appears to be
- based on the following assumptions: 1) All future shuttle flights will be
- successful. 2) The flight rate per year will be increased from three to
- four flights per year per shuttle. 3) No further shuttles will be built.
- 4) The lifetime of a shuttle is 50 flights.
