I don't trust the CRJ-900, and here is why...

There is a reason structural failure of this type hasn't occurred yet and it's not because these aircraft are new. Also, you're worried about the wrong phase of flight causing bending. Landing forces are much more extreme and there hasn't been a structural failure on the ground either.

Here is one of DC-9 deathtraps that should be banned from the sky.

Guys, stop feeding the troll. The guy did it just to get a rise out of RJ pilots.
Let this thread die.

It won't be bent because it is not static. The aircraft flies at a slightly positive deck angle with airflow hitting the bottom of the fuselage more than the top. Basic Newtonian principles mean the the fuselage is supported from the bottom. The positive deck angle also means you get some aerodynamic lift from the fuselage as well. Now you have Bernoulli lifting from the top.

Just so nobody is confused by this, the greatest potential stress on the tube is probably severe yaw or pitch that places the longitudinal axis at a large angle to the slipstream at very high IAS. But there are design criteria for that, and the tube shape is inherently strong (that's why pressurized airplanes use them). You can of course break the tube with a crash landing, ie very high VS, unflared landing.
