Some of the respondents above seem to view 'pilots' as a uniform entity with standard skill sets and operating ability. Sadly, it's not so. The number of Capts Sullenberger and Eric Moody are (from personal experience) limited. I had the pleasure of working with Eric Moody when he converted to the 400 and his personal skills matched, if not exceeded, his flying. Such people are rarities and to base future operating criteria on the premise that they will exist in the right place at the right time is (forgive the pun) 'pie in the sky'!
