LOL .. Never Leaves hangar ... Love it!!
I have a mate that was a Cabin Director before being offered to go 'Purser or Crew'.. so he went back to Y class as crew... anyway..
He said one of the tuff things was the amount of aircraft configurations you had to remember especially when aircraft are leased and brought in...
He mainly flew 747's but had been flying since before the introductions of 707's.. LOL I think he started flying DC6
