I was told years ago by an environmental engineer that the return on investment on water pipe replacement is about eight years. This is why I have such a hard time understanding why I always see that its not affordable to repair the lines. New water lines have a 50 year minimum life expectancy (in reality much longer with maintenance).

B-1 is one of those planes that’s “supersonic” in that it’s definitely designed to go over Mach 1, but is not operated that way on a day to day basis. No point in wasting a ton of fuel to go a little bit faster on a training flight. Also that baby probably gets jostled around more in her daily commute than in that aircraft.
