Boeing's Starliner launch tonight has been postponed "out of an abundance of caution" scarcely two hours before the historic liftoff. After years of delays and over $1 billion in cost overruns, the mission is set to be Boeing's first attempt to transport astronauts to the International Space Station. Once the issue is resolved with the upper stage, the United Launch Alliance Atlas V will carry the CST-100 Starliner capsule to orbit along with the two onboard astronauts — Butch Wilmore and Sunny Williams — from Florida’s Cape Canaveral at 10:34 PM local time Monday evening.
