Hi Ali, No you just had to slow down to about 220 knots, and the nose leg would pop up. It was just air pressure overcoming 3000 psi of hydraulic pressure. I suspect that the doors and leg might get damaged if the speed was allowed to increase too much. I think there is an example on U-Tube of a four ship take off from Wattisham where one of the aircraft's nose legs sticks down.
