Thread drift I know but still with the F100..... On Monday I flew Amsterdam - Bologna with KLM and noticed something with this a/c that I hadn't discerned before, ( I fly weekly on average, but not on F100s)...there seemed to be very small rocking or rolling of the a/c, (just a few degrees I would imagine), and at the same time a gentle yawing that appeared to be in sync with the rolling...was a very strange feeling once I had noticed it and it took a couple of bottles of wine for it to disipate. Is this a F100 fleet wide effect or just the situation on the day?
