Speed Of Superman

I have been thinking about these 4 hour flights from UK to Australia. Usually takes 21 hours. Well London to LAX (Los Angeles) is 11 hours, while London to Houston is 10 hours. Does this mean we could be in California or Texas in about half an hour? That would truly be a revolutionary step forward in travel, and one could argue even bigger than a certain Neil Armstrongs stroll on the moon. A truly bite sized world which would change a whole heap of things from work to visiting family/friends in distand lands.
Be great for sporting events too! You could be anywhere in the world by early afternoon, hell you could even have dinner at home before setting off! And be back for supper. The more I think about it, the more exciting it sounds. Super quick travel is the logical next step because it needs to keep up with our almost immediate communications. This is not the age of the snail, it is the age of speed and bouncing across the globe like a pinball with barely time to catch a breath. Everything needs to be done YESTERDAY from messaging to meeting.
