I thought I'd start a thread (I couldn't find one) about the potentially marvelous concept that is Skylon
and the slightly lesser known and even more conceptual A2
I have been following this since HOTL (too heavy at the back, apparently) and it's looking more and more feasible that an SSTO craft of this nature is possible now that the problem of frost control appears to be actually not a problem at all.
Are there any other comapnies pursuing similar technology? What does the assembled company think the feasibility of the project is?
Also, I get annoyed when the engines are referred to as working as jet engines. As far as I'm aware, they never do, they're always rockets.
