AnFi - surely you must applaud my method:
I have put forward a hypothesis that is technically feasible, contextually plausible and relevant to the thread. And, I have presented it as fact with no data, proof or evidence of any kind.
I can now sit back and refute any criticism of my hypothesis because I have laid the burden of proof on the critic (you).
I could have included some basic algebra to do with speed. distance and time equations but I could save that to support my hypothesis in a 'mathematical' fashion later.
I am surely your most successful student - I have learned much from you oh master - just none of it about helicopters.
