Has there ever been a successful 'bail-out' during an airliner test flight? Has there ever been an instance of a crew having to 'bail out' during a test flight of a commercial style aircraft (I.e Airbus, Boeing etc)?

I know that test flight crews often wear orange suits, parachutes during preliminary flight in case there is an issue.
