The potential downsides to mucking about with the space-time continuum.

Bell Textron Jet Pack – ‘Thunderball’
When James Bond swaggered on to the screen to do battle with Dr No in 1962, he had it all: the girls, the jet-set lifestyle, the licence to kill. The only thing missing was the mad gadgetry – the devious devices and lunatic conveyances that would become a hallmark of the long-running series.
All that changes in the opening moments of ‘Thunderball’, when 007 straps on a jet pack that looks like it’s made of toilet-roll tubes wrapped in tin foil and escapes from a French château in a chuff of green smoke after choking a grieving transvestite to death with a poker. Ludicrous and cool, it announced Bond as the boss daddy of big boys’ toys.
