They've just sent all three examples up for a fly-around Houston:
Three high-flying birds soar together for the first time since the 1970s | Ars Technica UK
Canberra - the aircraft that has been too useful to die for a veeery long time now!
Just as a matter of interest, just how expensive would it be thesedays to build something like that (or indeed the original) new? I don't mean load it up with massively expensive electronics, or design a whole new engine for ultimate performance. I simply mean build an airframe that looks the same, add the modern equivalent engines and a modicum of up-to-date avionics. Am I being cynical or would most of the money be lost to paperwork, political arguments, contract arrangements and set up time rather than actual metal cutting and joining?
