Red Dragon was always going to be one way, as a lander for some notional science payload. It was still a bit harebrained because it wasn't clear how to deploy that payload, whether rover or other, through the hatch. (I think I once saw

The first PDP-11 Unix was written in assembly, and was thus a from-scratch rewrite of PDP-7 Unix (also in assembly, for a very different machine). The rewrite into an early version of C came later, done initially for the same reasons you

Rome to Florence on high speed (Freccia) trais purchased three days in advance is ~$40 for an economy fare. Is someone quoting business class?

In countries with real high speed rail, this is not the case. Tickets on Italian Freccia trains are comparable to US bus fares between major cities. Acela in the US is expensive because it competes with planes - and laughably slow by world
