Having spent 9 days away on a trip and the last day at the chiropractors I am loving the dialogue.
GE90; you made some comments on landing As and Bs. Its a different technique and you can do smooth ones.
Airbus you derotate on landing and get a beautiful smooth landing with A330/343/345 (I know). Don't derotate and you will get a 'wobble' on touch of forward bogies. The middle wheels on a A345 hang front wheel down cf the mains which are rear wheel down.
Boeing you get a nice touch down after rear main wheel contact by NOT derotating. If you do it will smack on; freeze the (stupid and unnecessary) wheel in the position you touched and the rest should come down pretty nicely.
Overall experience as pilot and passenger I think A beats B for smooth landings but that is of course merely an opinion.
