WASHINGTON (Reuters) -The Pentagon's hypersonic weapon programs suffered a setback on Thursday when a booster rocket carrying a hypersonic weapon failed, people briefed on the test result said.

The test was intended to validate aspects of one of the Pentagon's hypersonic glide vehicles in development, two of the people said.
