Boeing tries first astronaut launch on delayed NASA test flight again

Boeing tries first astronaut launch on delayed NASA test flight again

Boeing's company’s Starliner capsule was due to rocket away at midday with a pair of test pilots to the International Space Station for a weeklong stay.

The test drive should have happened years ago. But problems kept piling up, most recently a leak that went unnoticed until the first launch attempt with a crew in early May.

NASA wants a backup to SpaceX, which has been flying astronauts for four years.

United Launch Alliance's Atlas V rocket is providing the lift from Cape Canaveral Space Force Station.
