We lost a space shuttle because NASA bowed to the same pressure and altered the composition of the foam insulation on the external fuel tank. It had been changed in 1997 to exclude the use of freon, which eliminated the preferred material chosen by engineers.
Excellent point...Fortunately this battery problem hasn’t caused a crash, as yet, but the incident that took place in Japan was real close.
Didn’t we lose TWO shuttles to the loss of heat shielding due to the change in the composition of the glue?
