Sushi On A Plane is a modification that allows a continuous sushi train to deliver meals to passengers.
Here's how it works: to allow create the delivery mechanism the arm rests require a basic modification. This modification takes the form of a simple extension that connects each of the arm rests to the one in front and the one behind each passenger to create a continuous pathway. Folding back the flaps on the arm rests reveals the belt drive that feeds the train of food along, looping around at the galley stations at various points on the plane to allow the sushi dishes to be placed on the train. Food moves from front to back between the seats. (this is possible using a specially contoured gap between each of the side by side seats) The sushi train then loops around and returns from back to front up the outside of the isle.
Of course using the toilet is not possible during food delivery time, but this is a minor inconvenience in comparison to having the novelty of a sushi train moving along on a plane.-- xenzag, Jan 13 2017 So is this vegetarian sushi?-- MaxwellBuchanan, Jan 13 2017 Sushi won't taste the same at the lower pressure present in airliner cabins during flight.-- 8th of 7, Jan 13 2017 True, but one generally asks the pilot to descend to 5000ft for meals anyway.-- MaxwellBuchanan, Jan 13 2017 There are numerous areas of your planet where attempting to descend to 5000 ft AMSL can suddenly become inconveniently loud and expensive...-- 8th of 7, Jan 14 2017 The conveyor could loop down from the armrest into an underfloor tunnel, before looping up again for the row in front. The little dishes could be gimballed so the sushi doesn't spill as it goes round the corners.-- pocmloc, Jan 14 2017 random, halfbakery
