"Boeing Jets Grounded Amid Investigations into Mid-Air Emergencies"

The Federal Aviation Administration ordered the temporary grounding of 171 Boeing jets after a panel blew off a new Boeing 737 MAX 9 jet in midair. Safety checks hit a snag over paperwork, and the planes will remain grounded until the FAA is satisfied that they are safe. The missing panel, which is likely to have landed in the western suburbs of Portland, has not yet been found. The incident has put Boeing back under scrutiny as it awaits certification of its smaller MAX 7 and larger MAX 10 models.
