Having come from the Viscount whose props were close to the ground and wings were required to be level for touchdown,
This early myth about the Viscount in Xwinds was only relevant if the aircraft was not flared for landing.
In fact the controlled-slip X-wind approach so beautifully demonstrated by American autopilots such as Tristar and Boeing 757/67 was perfectly feasible (manually) on the Viscount - with a touchdown bank of no more than a couple of degrees.
Otherwise the regularity achieved on winter Scottish island services would have suffered considerably!
With apologies for thread drift. (No pun intended).
