Personally I'm scared to death of these types of over the ocean night flghts, but then I think of my instrument training using all those little, old fashioned guages.
I saw a video not all that long ago of a guy taking off in IMC in a 407 (I think someone called it that?) but he had this huge glass cockpit display with what looked like an enormous artificial horizon! I thought, "Damn! how much easier it must be to fly staring at that huge ass thing compared to that tiny one I once had to use?!"
Did this 139 have a glass cockpit?
