The following advice is from the book Handling the Big Jets by D.P Davies, who joined the British Air Registration Board in August 1949 as Chief Test Pilot and carried out the certification testing of the world's first jet transport aircraft in 1950.

Page 177 headed Reduced Roll Freedom on the Ground.
"During the rotation on the ground, the outer part of a swept wing, because it is aft of the main gear (which is the pivot of the manoeuvre), rotates closer to the ground and the wing tips and flaps can get very close indeed. Under these conditions only a few degrees of roll freedom may exist before something scrapes the runway.
Life is more complicated yet, because it must also be remembered that swept wing aeroplanes roll hard with yaw. The control of this roll has to be nicely matched by the lateral control, bearing in mind the possibly dis-continuity in roll against lateral control application when the spoilers take effect.

So take care when operating in cross winds. On take-off, set in a little into-wind aileron control quite early in the take-off run whether or not you feel it necessary; this will stop the down wind roll which will otherwise occur just before lift-off. Then, throughout the rotation and lift-off, make sure you keep the aeroplane substantially level laterally. On landing, don't get too active on the ailerons close to the ground. Apply enough but not too much and bear in mind the approximate spectacle angle at which the spoilers start to augment roll control. Avoid the divergent lateral oscillations which can develop and eat up your roll clearances in no time"

There is much more good gen about cross-wind operations in the next few paragraphs to be found on page 178.
In 1967, Flight International made the following comment in their review of Handling the Big Jets. "...this is no dry textbook. It is a tremendous, but notably readable, vade-mecum of jet transport flying qualities and design characteristics intended primarily for pilots who have yet to make the transition to jets, but which is packed with information of value to the most experienced of captains."

Interestingly, it has been my experience as a flight simulator instructor that almost no pilot I have talked to in the past 25 years has even heard of, let alone read this marvellous book. It was first published in 1967 and reprinted in November 1999. With the now unprecedented shortage of airline pilots around the world, flying school operators would be doing a great service to their students to ensure they first read Handling the Big Jets before embarking on an airline pilot career.
