JetsGo MD-83 engine not working?

I flew JetsGo flight 178 (Toronto to Vancouver) on 19 January 2005. The
equipment was an MD-83.

I'm convinced the right-hand engine was not operational! I could not see
the turbofan spinning (looked stationary) and the flight took about an
hour longer than scheduled (they blamed strong headwinds).

Is this possible? Can/should/is it legal for a flight to take off and
fly an entire route with one engine? How much flight time would this add?

Are there publically-available safety logs that would record if this was
the case?

How are JetsGo's safety standards?

Lots of questions!

Thanks
