KUALA LUMPUR, Malaysia (AP) — An air search in the southern Indian Ocean for possible objects from the missing Malaysia Airlines plane described as the “best lead” so far ended for the day without success Thursday but will resume in the morning, Australian rescue officials said.

The four planes were checking to see if two large objects spotted in satellite imagery bobbing in the remote ocean were debris from Fight 370 that disappeared March 8 with 239 people on board.
