"Impossible"? (沒有可能)?

Napoleon is alleged to have said, "The word 'impossible' does not exist in the French dictionary!".

From a little known army captain from the French colony of Corsica who protected the Republican National Convention on 13 Vendémiaire Year 4 (5 October 1795 ) of the Republican calendar adopted by the National Convention in 1791(two years after the French Revolution started with the storming of the Bastille on 14th July 1789) when it was under threat from the Royalist forces led by returned emigré Comte d'Artois, aided by 2,000 British troops in what is now the 2nd arrondissement ( or district) of Paris, when an insurrection broke out there Napoleon quickly disposed of it with what the British historian Thomas Carlyle described as "a whiff of the grapeshot" ie. the firing of some canon balls and thereafter rapidly rose in power until this "son of the Revolution", by an ironic twist of history, proclaimed himself Emperor of France on 2nd of December 1804.

But whatever may have been the truth of that bold assertion, as far as scientists are concerned, something previously thought "impossible" has lost a little of its meaning now. The evidence appears in the following video posted by Windoor two days ago about a wind tunnel acrobat called Leonin Volk. 

"Impossible!". Still dare to fully and confidently repeat that word again now?
