Havent heard this one but I WILL investigate. Working here in Dubai so I shall give an update when I get back to work on saturday.
For the record there are geometric over centre locks on ALL of the landing gear, however it is the positioning of the gear which does make the differance. Yes there is a possibility of the body gear running foreword but it is more likley just to crack the over centre lock than fully retracting. The weight on the wing gear makes it proctically impossible to retract on the ground without jacks or pits. The important 1 that you MUST REMEMBER! Again MUST romember. Is to put the pin into the nose gear. Otherwise CRUNCH.
Foreman not happy and you looking for another job! Well cant take a joke you shouldn't have joined.
