DARPA’s HTV-2 crashed because it blew off chunks

DARPA’s HTV-2 hypersonic test vehicle crashed due tomaterials being worn off the airframe as a faster rate than predicted. But on thegood news side, the aircraft proved to be more controllable than the engineershad expected. The DARPA study is being used to inform the US Defense Department’son-going Conventional Prompt Global Strike efforts–which would hit a target anywhereon Earth in under an hour.

And still pretty expensiveprobably…

So, is it worth the time, effort and money? Discuss.
