As a non-engineer, it seems like we could solve a lot of the issues with these things today. 1) Active control is standard fare on a ton of places these days - it's 'normal' for a military jet to be aerodynamically unstable. 2) 2000lb of combined thrust without melting the gauges? Check - better insulation, jet efficiency, and electric power all can help here. 3) Funding? C'mon Elon - you know you want one!
