That seems to me to be a flaw in the philosophy of hiring noobs straight into an airline cadet scheme or similar. Where's the real breadth and depth of command experience going to come from for these people? I may be wrong and I will certainly listen to other opinions but in my gut I'd rather be a pax on a plane flown by a 10,000 hour pilot who had worked for a dozen different operators in half a dozen different countries than a 10,000 hour pilot who had done it all on "george" or the sim for the one outfit and on the one type. Extreme cases obviously, but you get my drift. Anyway, it's a bit of a side issue.
