The National Transportation Safety Board is expected to give an update Thursday on the investigation into the Boeing 787.

Investigators have been looking at the lithium ion batteries to find out why they are catching fire. No fix has been announced, yet.

All 50 of the 787s that are in service around the world have been grounded during the investigation.
