Was the 'real deal' or much ado over nothing? Back in the day, that's pretty much what an engine start on a L1011 looked like.

Very strange that the Squawk Headline mentions the Airline, but not the aircraft type. JUST KIDDING!! I know this was an incident involving an Airbus, an A-330 in this instance, and not a Boeing.
