re: This is very different!
A second Orbiter was destroyed, killing the crew.
The Shuttle shows its fragility.
In 1986, the decision to build Endeavour was taken and its funding was approved without problem.
I remember being very worried when administrator Fletcher said (in 1988) that the space station will not be launched (or built) by a Shuttle derived HLLV, but only by the Shuttle.
Any future manned space program would totally depend on the reliability of the Orbiter.
I'm afraid things will have to change and this will require leadership.
Or else, the manned space program might vanish.
