BhutanH130 - it very much depends on your perspective as to how you view this 'stunt' - I don't know your experience or age but I am looking at it from a career of 35 years of military flying that includes a great deal of low flying, fighter evasion, air combat manoeuvring and other similar disciplines so in that context a simple wingover really isn't a big deal.
If all you do is fly straight and level from A to B with pax at a safe height then it probably looks horrendous and seems the most heinous crime to fly such a manoeuvre.
Apart from anything else - it looks like fun - because it is - something that seems to be progressively legislated out of aviation.
