Just saw the following picture at airliners.net and the note which says, " Take a close look a the engineers. Yes there are two of them, one is waiting for his turn to climb up the nose-wheel and into the aircraft. When the Chinese emperor embarks on his flights he bring a team of engineers, who supervise the start-up procedure after which they board the aircraft in this rather unconventional."
Of course my first question is : WHY?
Subsequently, where do you end up climbing through the nose gear? Anyone - been there - done that - (I mean climbing!)
