SpaceX - Falcon Heavy - Flight Animation

From the video description:
Published on Jan 27, 2015
When Falcon Heavy lifts off later this year, it will be the
most powerful operational rocket in the world by a factor
of two. Thrust at liftoff is equal to approximately eighteen
747 aircraft operating simultaneously.

The one thing I doubt we'll see in the test launch is all three of the
first stage cores landing at the launch site. As far as I know, SpaceX
does not yet have permission to land a core at The Cape. I'd imagine
permission to land three (two almost simultaneously) in relatively close
proximity will take an additional level of permission beyond that.

This video is surely to show the future direction. In other words,
before ULA officially announces details of their "next generation"
launch vehicle, SpaceX is repeating what they plan to do with Falcon
Heavy. If Falcon Heavy can demonstrate fly-back and landing of three of
four Falcon Heavy first stages before ULA starts flying their "next
generation" system, the learner will truly be the new master.

magically make space launch cheaper is nonsense -- LOX is much cheaper
than advanced airbreathing engines, and so are the tanks to put it in
and the extra thrust to carry it." - Henry Spencer
