The singer was shaken but undeterred; she caught another flight home a few hours later.

“I’m pretty spiritual about it,” she said Wednesday. “I turn it over to God and think, ‘There’s nothing I can do about it.’ And I also think, ‘What are the odds?’ I’ve been flying for 18 years and had one emergency landing. That’s pretty good.”

Yearwood, her sister and some friends were returning Aug. 18 from a three-day, 60-mile walk in Boston to benefit Susan G. Komen for the Cure breast cancer research fund when they heard a loud pop.

Yearwood, 43, said the front left window of the plane had cracked.

“We never lost cabin pressure, so we didn’t have to use our oxygen masks. By the time we got on the ground, the crack on the front of the plane’s window was huge, and getting bigger by the second,” she said.
