Thanks to all who have added to the thread,it has made interesting reading already.The car analogy is good and it also shows our loyalty to brand too.It is quite usual for someone to stick to one make of car through several models and pilots definately seem to gain a real Boeing/Airbus loyalty over their careers, even if it is down to the coffee table availability!
Would be great to get 4 gold's opinion later too,as it is ideal to be moving from one to the other.
Shockingly i have not thought of asking my fellow engineers how they are to work on! I have been concentrating on reliability and service bulletins etc.Will rectify tonight.Thanks for the wake up mavrik.
