ARMONK - An IBM executive from Texas is one of three Americans onboard a missing Malaysia Airlines plane that vanished yesterday on its way to China.

Philip Wood, 50, was identified as one of the unaccounted-for passengers onboard Malaysia Airlines flight MH370, his brother confirmed. Wood had been working in Beijing for the past two years and his family says he was preparing to move to Kuala Lumpur, the capital of Malaysia.

In Armonk, where IBM is headquartered, residents and IBM workers say they're shocked about the news.

Officials say the plane vanished yesterday without a trace. On Sunday, Vietnamese authorities spotted a rectangular object believed to be from the plane in the waters off Vietnam.
