Crab ... I think you are purposefully missing the point most are making . They are not saying he overstressed the aircraft or that he should have it grounded !!!! You have set your stall out and are not going to back down for anyone . Just ask yourself the question ..... if my daughters new boyfriend came to pick her up on his motorbike and pulled a wheelie all down the drive ...would you
1) Be impressed at his skill and think your daughter would be very safe
2) Think ...what a penis , I don’t want my daughter travelling with him .
And there is the point .... a well executed wheelie is not necessarily dangerous or bad for the bike ......but it is very often both !!!
