The Register's Geek's Guide series for explorers who love feats of tech and engineering prowess took a trip to the European mainland to see exhibits ranging from an Air France Concorde and a Soviet Tupolev Tu-144 "Concordski" to a Buran prototype, alongside various industrial marvels.

The spot? Well there are two of them: The Speyer and Sinsheim museums, both well worth a visit the next time you're in southwest Germany.

The two museums can be accessed by driving an hour south from the closest large airport, Frankfurt, and represent an effort, beginning in 1981, by a gang of vintage enthusiasts keen to show off their vehicles. The collection has since grown to include a variety of military hardware, a good number of aircraft, and, of course, the supersonic airliners and the Buran prototype. //

A two-day pass is €52 or €42 for children between 5 and 14 and includes a show at the IMAX theaters on each site, although we didn't bother with a viewing since there was more than enough at each museum to look at it.

There is also a parking charge at both museums.
