Facebook COO Sheryl Sandberg -- I Was Supposed to Be on the Plane That Crashed!

Status Update: Facebook COO Sheryl Sandberg was almost a passenger on the plane that crash landed in San Francisco today ... but a last minute decision to change flights spared her and her family a harrowing ordeal.

Sanderg posted on her FB page (where else?) that she switched flights at the last minute so she could use her airline miles to pay for her family's tickets.

She explained, "Our flight was scheduled to come in at the same time, but we were early and landed about 20 minutes before the crash."
