When the front breaks off, the center of gravity of the remaining fuselage suddenly shifts far aft of the wings, which are still generating lift. The net result is a large moment rotating the reminder of the plane into a "nose high" attitude (unfortunate terminology).
The engines continued to provide thrust after the explosion for this to happen, correct?

The nose section separated after the explosion causing the rest of the aircraft to pitch up. The aircraft continued to climb because the engines were still producing thrust. The rush of air into the open hull of the fuselage, along with the change in center of gravity immediately sunk the tail and the remaining aircraft climbed until aerodynamic stall.

What's the title of the documentary?

The net result is a large moment rotating the reminder of the plane into a "nose high" attitude (unfortunate terminology). The remaining fuselage climbs until the wings no longer generate enough lift to keep the plane in the air on their own. At this point it continues on a ballistic arc until all remaining vertical speed is bled off, gravity wins, and the fuselage plummets to its ultimate fate.
did you stay at a holiday inn express last night?

Yes, that is correct.

Yes, that is correct.

Probably the best possible response. Wonder how many people on here even know what Kerbal is.

The remaining section of the airplane wouldn't have climbed over 1000ft without engine power, no. Remember, there are 4 engines still producing climb power when the explosion occurred. The wings would have stalled much sooner if only propelled by the kinetic energy of forward motion at that airspeed, and without engine power.

They climbed higher because there's less oxygen up there and they thought it would put the fire out......

I have a difficult time believing that the rest of the fuselage remained intact.

It didn't. The general belief based on eyewitness testimony and ballistic analysis of where they found different pieces of the wreckage is that the rest of the plane progressively broke up starting roughly 30 seconds after the forward fuselage separated from the rest of the plane. So, for some time after the initial failure, the portion of the plane that the front fell off of flew uncontrolled until aerodynamic forces started to break it apart.

If there was an explosion, ie thrust, that produced force so the wings produced lift, it will gain altitude
Yep. Challenger was a good example. Went up another mile or two after the explosion.

Can you reduce your explanation to ten words or less for the slow learners?
Posted on 8/5/16 at 6:47 pm to John Keating
seriously, this is the one conspiracy theory I believe in. Truly.

Let's see...
The first post: Front fell off. Rest pointed up. Went up. Fell down.
The second one: Where pieces landed told investigators when they fell off.
