NEW YORK (AP) - An internal memo from JetBlue condemns flight attendant Steven Slater's deploying of a plane's emergency slide and says the airline still doesn't know what prompted his now-famous exit.

In a memo obtained by The Associated Press, JetBlue's chief operating officer says the airline is still investigating the
incident, but that no one has yet corroborated Slater's version of events.

Slater's attorney says an uncooperative passenger prompted his behavior. In the memo, JetBlue, based in Forest Hills, N.Y., says several passengers on the Monday flight "have given interviews that tell a different story."

Slater has been hailed as a hero on social networking sites for what seems to be the ultimate "take this job and shove it"
moment.
