As a "Fairey" with many boring flights on MR1's and MR2's, I never noticed it either until it was pointed out to me when a "Dry" and Rigger were talking about it over steak and chips out of Lajes one day. I admit it depends on wing loading but I don't remember a flight afterwards without seeing it...I used to hate some of the MAD manoeuvres afterwards. Not that they are liked anyway....
