That's correct AlphaSim became Virtavia, however, glowingheat.co.uk has nothing to do with either.
I am the modeller behind the B-58 Hustler for FS9 and the FS9 and native FSX SR-71 Blackbird. I'm going it alone so to speak for a variety of reasons, none of which are suitable for public airing. I started with AlphaSim back in 2003 and have been around a lot over the years, but I have only released a small number of aircraft.
There may possibly be a new B-58 Hustler for FSX at some point in the future now that it looks like FSX has extra life left in it.
Regards,
David.
