Remember doing wet Xwind trials with short landings at BD prior to the Nimrods going down to Stanley after we had kicked their a--es. The max Xwind we tried was 40kts and, using the wing down technique, it was not a problem. The test plan required the final landing to be stopped using max anti skid. Interestingly, this caused all the upwind tyres on both bogies to burst. It was quite exciting. It was concluded that this was because the Xwind component was causing the undercarriage legs to slightly "lean over" which, effectively, gave the upwind wheels less purchase on the runway. It was the only time I have heard multiple tyre bursts. It was nice to have had a cast iron excuse!
