It might be comparing apples to purple oranges; however, I was hired at Gemini on the MD-11 and went through new hire training on it. It wasn't all that difficult and the airplane is a piece of cake to fly. Very transparent sytems and nice flying characteristics.
Some of the gouge stuff we had going through training was FedEx and UPS stuff. The MD-10/11 differences would be a pain but other than that, new hires should be able to handle it.
So, Mr. Smith, I'm ready for my class date. Please contact me at your convenience.
