OK, so who are the so-called professional pilots who think it was safe - come on, own up then we can treat you as the numbnuts you really are when you next post on a subject?
I understand that in the UK, a display pilot will not get a licence to display below 50 feet (15 metres) - I doubt if the wingtip was much more than 2 to 3 metres above the ground in this manoeuvre - bear in mind that display pilots will normally be displaying aircraft with wingspans under 50 feet, whereas the A310 is what, 60 metres?
Go on - dare you....
