Delta Air Lines flight 169 to New York returned to Barcelona shortly after takeoff after flying through a hailstorm. The A330 is still grounded.

A Delta Airlines flight was forced to turn around within an hour of takeoff after flying through a hailstorm over the weekend.

The airline must inspect more than 100 aircraft before they can fly again after the storms brought quarter-inch hail to the region. The affected planes were on the ground during the storm.
