Authorities say a Texas man was on board Malaysia Airlines Flight 370 when it went missing en route to Beijing.

North Texas native 50-year-old Phillip Wood is among the 239 people missing after air traffic controllers lost contact with flight 370.

Also on board were 20 employees of the Austin-based technology company Freescale Semiconductor.  That group includes three Americans.  

Search crews are still searching for the plane or wreckage.  Searchers found two large oil slicks off the southern tip of Vietnam Saturday but no wreckage has been found.

There is a lot of speculation on what might have happened to the plane after it was found that two passengers listed on the plane were found alive and well.  Their passports had been stolen in Thailand last year.
