Re: Hounslow 17:56 weekdays ...
So whilst we might feel all sorts of warm feelings about Concorde, it's worth noting that we (and our parents) paid for it, and never reaped the rewards.
Depends on where you look for the return on the initial investment. In Concorde's case, it gave us (ie Europeans) Airbus, and in terms of economic stimulation and return that has been excellent. There's hundreds of thousands of people engaged in gainful employment today as a direct result of the Concorde treaty being successful (ie yes, we can work together, let's do more of that).
Ok, so Airbus might have happened anyway, but Concorde did set the scene rather well.
