Think it's quite a bit later than that. '60s? But they were good - needed
a large motor to hover so had plenty suck. Not sure the hover idea worked
well, though. Depended too much on the surface it was on.

Definitely 1950s, but it stayed in production well into the 70s.

From http://www.74simon.co.uk/867.html:

Launched in 1954 in the USA and 1956 in the UK, [...] The Constellation
was made even flashier in 1958, when a fixed metal skirt was fitted to
the bottom of the machine, enabling it to literally float on a cushion
of its own exhaust air.

Ah - right. They made an earlier version with the same name which didn't
hover? Hardly memorable then - just a sphere on wheels.
