- And don't forget the G and H model B-52'as. Those are at least 30 years
- old and still flying.
- I think I read somewhere that many old planes are so durable that the primary
- problem in keeping them flying isn't how well they were designed but
- maintaining a supply of spare parts (i.e. WWII aircraft still flyable today).
-
- Supposedly this is a similar problem for the shuttle--only 5 flight
- capable orbiters built in past 13 years makes a very rare craft, and thus
- creates a maintainence problem due to their limited numbers.
