nose cones
just a couple of easy questions!
why do many ba a/c have their nose cone a different colour to the rest of the fuselage? many seem to be white with a black stripe around it.i seem to have noticed more on 75's than anything else but this could just be me.
also
why do u hear "chimes" in the cabin when an a/c is starting up? by chimes i mean the same noise as the cabin crew call buttons.
also (last one dont worry)
why are the left hand doors usually used to board slf? is this purely down to the fact that most boarding gates are configured this way,or is the a more cunning reason?
just curious!
