Its Falcon 7X and Falcon 900 are the only trijets still in production today. The S-duct is very aerodynamic. However, they are not only very complicated to make, but also expensive. McDonnell Douglas opted instead for a “straight-through” set-up with the engine mounted in the tail fin for its DC-10 and MD-11.
Will trijets come back?
Alas, the trijet design may never make a true comeback and just like how the trijet led to the downfall of the four-engined aircraft, it seems the very same has happened with the introduction of twin-engined aircraft.
Why did they stop making trijets?
The biggest obstacle trijets face today is operating costs, primarily fuel efficiency, as a three-engine design almost certainly consumes more fuel than a comparable two-engine design. This also greatly increases the difficulty of marketing a new trijet aircraft today, especially for passenger service.
Why are there no 3 engine jets?
For the same reason carriers made shifts from four-engined aircraft towards three-engined aircraft, airlines also shifted from three-engines to two: lower-costs and greater efficiency. For tri-jets, it wasn’t just in terms of operation and maintenance – it also extended to the cost of manufacturing.
Are Tri-jets still made?
Most production of trijets ceased in the 1990s, with new twinjet aircraft such as the Boeing 777, 787 and Airbus A330 replacing them on most routes, whilst a small number of new A320 and 737 variants replaced them on some short-haul routes.

Are any l10 11 still flying?
In the early 90s, Orbital Sciences Corporation modified a unit to be part of the rocket-launching process. The plane was transformed from an Air Canada passenger model, with Air Canada taking part in taking satellites to space. This unit still flies today, keeping the L-1011’s legacy alive.
Can a 747 fly with only one engine?
When it successfully performed an emergency landing, three of four engines were running, although not on full power. The case of BA9 was a real-world demonstration that a Boeing 747 on just one engine was still not enough to gain, or even maintain altitude.
