Picking up on 'None' using extra TR when starting to slide onto the stand and the comments on VC-10 ...
In a similar thread last year, I recall a comment from a ground handler on a VC-10 in icing conditions many moons ago. It went along the lines of,
"The VC-10 started sliding towards the terminal, apparently with no grip! There was big noise from back end of VC-10 and VC-10 stopped moving in a second!!"
VC-10?
