Personally I think that for inspiration factor alone, this project is worth every red cent.
In an aerospace era when excessive financialisation or risk avoidance drives just about every decision made - it stands out.
No doubt it's expensive - and there's danger involved.
Economic ROI - who knows?
(But then who knows about any ROI - often no more than a blimmin' licked finger in the wind and a guess).
We're talking aerospace hi tech, extremely loud noise, the beautiful smell of Jet A1 and rockets into the bargain, big cars and insanely excessive speed!
What more could you ask for?!
Good luck to the team.
