What I am gleaming from this interesting discussion, and respect to the individuals who were involved in this incident, is the non understanding of certain aspects of twin operation. I am also always intrigued about the single verses twin arguement where the 'two are better than one' scenario is always given as better. I have rarely agreed with that sentiment.
I have a friend who has bought a lovely Baron. I asked how often he flew it, once a month VFR, cannot find the time. I thought to myself, Dear God, sell it.
Does anyone happen to know the history of the particular 310? Airframe time was quite low.
