BOAC,
However, there does appear to be some misinformation on this thread. Shy Torque - even as a rotating palm-tree driver you need to think about your comment 'rather than too low'!
No sign of 20-30kts on 'base leg' - or anywhere, come to that - all within 'limits'.
I based my comments on post#13 from EDMJ, who presumably has seen an initial report.
