Can anyone please explain the logic behind the Trident's nosegear being offset to the left and retracting sideways to the right? I have never seen this on any other aircraft and it certainly looks very odd when viewed from the front.
On another note, did you know that the Trident 3 had a fourth engine? It was located between the centre engine and the rudder above and was a Rolls Royce RB.162-86 booster with a thrust of 5 250 lbs. It was only used during take-off.

It is an interesting a/c isn't it? In some circles it was referred to as the world's only "three and a half" engined jetliner. I understand that the booster turbo jet was added to increase takeoff performance (obviously) but the RR speys where pretty much at their economical limit of upgradability. It was cheaper to add the booster which could also be used during other phases of flight. The Trident was also the first airliner to be certificated for automatic landing in zero visibility. As far as the unusual landing gear, particularly the side retracting nose gear, I can't help you there. Perhaps this arrangement would make for an easier manual deployment since it wouldn't be competing with the wind as much as a forward extending gear. Regards, Doug.

Yes it's true the gear turned 90 degrees then inward. Each bogie had 4 tires...not like you'd see on a 747 but all on a single axle, 2 on each side of the strut..thats the primary reason for the 90 degree rotation
