I saw White House Down this weekend and there is a scene where they take off a VC-25 (Air Force one) from Andrews AFB and say that they will be at 30,000 feet in 45 seconds. The scene in the is clearly CGI and its a movie, but is that actually a possibility for this aircraft considering it is a USAF modified 747 and a presume rarely at MTOW ??
Would this also be something that Boeing and other manufacturers would have had to do with their planes when testing it before certification??

That would be a particularly cool 747. Presumably it could go near-vertical.
On a particularly silly note, would it be possible to put some humungous, giant, fighter-style rockets with afterburner onto something like a 747, in order to achieve such ludicrous performance? Would the force just rip the pylons off the wing? Has anything even vaguely similar been tried?

Conveyor belt, anyone? Perhaps a phalanx of JATO bottles? But, perhaps, most importantly: A complete disregard for aerodynamics and physics. Which is just Hollywood staying true to form, as in being purveyors of entertainment and not facts.

Quoting StarAC17 (Reply 15): On another note if a 747 was climbing at 10000ft/min, what would be the G force felt by a passenger?
A steady-state climb is a 1G maneuver - it's the getting into that climb (upward acceleration) that'll cause the G-forces. If the transition from level flight to the climb were done gradually (which would admittedly cost time), then the passengers shouldn't feel much of anything.
