Aircraft Overstressed? Help please

[r3dt4g]

Im running threw a tutorial that sort of explaining me how to fly a jet (747)
now except the fact that the tutorial dosnt really explains anything
i manage to follow his instructions to lift off which i know how only
from my previous tutorials (flaps > throttle > pull up > you are airborn)

But with this Jet looks like something is wrong
I taking off, raising flaps, gear, pulling up a little, then i hear alarm sound
nothing on my panel indicates any problem (no lights nothing)
so i keep gaining altitude, and then it ends.
game stops and it says "Aircraft Overstressed"

What is wrong?

Too fast, the alarm is "overspeed" then the aircraft breaks up in mid air because of stress.
Try not to exceed 250 knots below 10 000 feet.

I don't like tutorials because they mess around with us too much, but if it lets you do it, you can un-check the "overstress damage" option

Folks need to remember, as you get into jets, over speed even in a climb is possible...

If you've been flying props, its relatively hard to go over max speed in level flight or climb, but a 747 can easily blow itself to bits if you don't back off..

As the earlier poster mentioned, keep it around 250 below 10k feet... Then up to about 335 above that.

As you get higher you need to watch the max as it decreases with altitude. Switching to Mach numbers will help you, as the 747 can fly around mach .80 without fear up to about 40k feet.

Airliners don't fly around with the throttles pushed up to the stoppers. Thats whats killing you, r3dt4g.
