Elon Musk's latest rocket concept - the 'BFR' - would take you anywhere in the world in under an hour, and most destinations in about 30 mins.

Oh, that's plus, presumably, three hours for check-in, security and passport control. And another for baggage collection and immigration when you get there...

However, if he can fix that - i.e. sort out the airports too - then going to Mars should be easy in comparison...
