Curtiss Twin JN (JN-5, Model 1B)
Role Experimental biplane observation aircraft
Manufacturer Curtiss
Introduction 1916
Primary user United States Army Air Service
Number built 8

Based on the successful Curtiss JN-4, the Twin JN used the same wing structure, but the wingspan was extended by enlarging the center section. Lateral control was achieved with the tail of a Curtiss R-4. The Twin JN was powered by a pair of 90 hp (67 kW) Curtiss OXX-2 engines located between the wings.

One aircraft was evaluated by the United States Navy as a twin-float seaplane.

gollark: Cleverness? How is there cleverness in using resources to make a chunkloader...?
gollark: If we had infinite processing power on all servers, I expect that chunkloading wouldn't exist. Unfortunately we don't so it does, and it seems stupid to spend resources on things to get around, well, unintended features.
gollark: Sure, I don't see why not.
gollark: I'm sure that if Mojang *could* they'd get rid of chunks and have everything be loaded constantly. Unfortunately they can't.
gollark: It's like saying that render improvement mods are cheaty because low FPS is a part of the game.
