Gday Nev
CASA aside - I will go so far as to say it WILL happen eventually.
My dad many times told me that at some time in the 40s his dad looked at the moon and said man will go there one day. My father laughed at him.
Even now, when I look into the night sky I ponder how the fark does a guy fly to the moon. The world is electric these days - aircraft powered
by electric motors seems infinitely more possible than flying to the moon, than taking a heart of one dead dude and putting it in another person,
than hitting send on an email and have it pop up on a screen on the other side of the planet instantly, hell, even more likely than a 575 tonne A380
getting airborne. Electric engines powering an aircraft seems like a piece of piss in comparison to many achievements of the human race.
