Oh OK then. Because ONE person got a job at Cathay (presumably as a S/O on the "C" scale), this somehow proves the Q400 as worthy step?
Don't think so. You are just revealing your lack of industry knowledge.
The reason you don't want to answer the points here is that, well, you can't. We all know how fast the 400 is (or rather, isn't), and what some of its problems are. The other issues are obvious to anyone who has flown a jet.
Has it ever occured to you to wonder why nobody else wants to buy the thing? Here's a thing you can do... go to the Bombardier website and count the number of Q400 orders, then count the number of CRJ orders. You will note that they seem to be selling the CRJ at about 10:1 compared to Q400 sales.
Keep waving the flag, though...
