In automotive engineering, the firewall (American English) or bulkhead (British English) is the part of the automobile body (unibody or body-on-frame) that separates the engine compartment from the passenger compartment (driver and passengers). It is most commonly a separate component of the body or, in monocoque construction, a separate steel pressing, but may be continuous with the floorpan, or its edges may form part of the door pillars. The name originates from steam-powered vehicles, where the firewall separated the driver from the fire heating the boiler.
In aviation, a firewall on an aircraft isolates the engine(s) from other parts of the airframe. In single-engine aircraft, it is the part of the fuselage that separates the engine compartment from the cockpit. In most multi-engine propeller aircraft, the firewall typically divides the nacelle from the wing of the aircraft, or divides the nacelle into two zones.
A firewall is a fire-resistant barrier used to prevent the spread of fire. Firewalls are built between or through buildings, structures, or electrical substation transformers, or within an aircraft or vehicle.
An airliner is a type of aircraft for transporting passengers and air cargo. Such aircraft are most often operated by airlines. Although the definition of an airliner can vary from country to country, an airliner is typically defined as an airplane intended for carrying multiple passengers or cargo in commercial service. The largest of them are wide-body jets which are also called twin-aisle because they generally have two separate aisles running from the front to the back of the passenger cabin. These are usually used for long-haul flights between airline hubs and major cities. A smaller, more common class of airliners is the narrow-body or single-aisle. These are generally used for short to medium-distance flights with fewer passengers than their wide-body counterparts.
A nacelle is a streamlined container for aircraft parts such as engines, fuel or equipment. When attached entirely outside the airframe, it is sometimes called a pod, in which case it is attached with a pylon or strut and the engine is known as a podded engine. In some cases—for instance in the typical "Farman" type "pusher" aircraft, or the World War II-era P-38 Lightning—an aircraft cockpit may also be housed in a nacelle, rather than in a conventional fuselage.
The OKB-1 '140', was a jet bomber produced in the USSR from 1947.
Coupé de ville — also known as town car or sedanca de ville — is a car body style produced from 1908 to 1939 with an external or open-topped driver's position and an enclosed compartment for passengers. Although the different terms may have once had specific meanings for certain car manufacturers or countries, the terms are often used interchangeably.
There are many types of car body styles. They vary depending on intended use, market position, location, and the era they were made in.
A bulkhead is an upright wall within the hull of a ship, within the fuselage of an airplane, or a car. Other kinds of partition elements within a ship are decks and deckheads.

The Vickers Windsor was a Second World War British four-engine heavy bomber, designed by Barnes Wallis and Rex Pierson at the Vickers-Armstrongs factory at Brooklands.
A glossary of terms relating to automotive design.
The configuration of a car body is typically determined by the layout of the engine, passenger and luggage compartments, which can be shared or separately articulated. A key design feature is the car's roof-supporting pillars, designated from front to rear of the car as A-pillar, B-pillar, C-pillar and D-pillar.
A vehicle frame, also historically known as its chassis, is the main supporting structure of a motor vehicle to which all other components are attached, comparable to the skeleton of an organism.
The 900/800 class railcars were diesel multiple units built by the New South Wales Government Railways between November 1951 and November 1960.
A limousine, or limo for short, is a large, chauffeur-driven luxury vehicle with a partition between the driver compartment and the passenger compartment which can be operated mechanically by hand or by a button electronically. A luxury sedan with a very long wheelbase and driven by a professional driver is called a stretch limousine.
The RWD-11 was a six-passenger feeder-liner designed and built in Poland from 1932.
Ansett-ANA Flight 149 crashed near Winton in Queensland, Australia on 22 September 1966, killing all on board. The Vickers Viscount aircraft departed from Mount Isa, Queensland, Australia for a 73-minute flight to Longreach. Forty-four minutes after takeoff a fire started in one of the engines. The crew were unable to extinguish the fire or feather the propeller so made an emergency descent with the intention of landing at Winton, a small town along the route. The fire spread to the fuel tank and weakened the wing structure so that a large part of the left wing broke away and the aircraft crashed. All twenty-four occupants were killed. The accident remains the fifth-worst in Australia's civil aviation history.
On 31 January 1945 a Stinson Model A aircraft departed from Melbourne for a flight of 127 nautical miles (235 km) to Kerang, Victoria—the first leg of an Australian National Airways regular scheduled service to Broken Hill, New South Wales. It crashed 50 nmi (93 km) from Melbourne. All ten occupants were killed in the accident. The aircraft was one of four Stinsons imported in 1936 by Airlines of Australia (AoA). Three had now crashed with the loss of 17 lives, and the fourth would not be permitted to fly again.
A bruck is a type of bus or coach built to combine goods and passenger transport where it is most profitable or most convenient compared to separate vehicles. The word bruck was used in North America. In Australia they were known as passenger-freighters. In Europe they are known as Kombinationsbus (German), seka-auto (Finnish), kombibuss (Norwegian) and godsbuss (Swedish), with even the nickname skvader. They have for practical reasons mostly been built on front- or mid-engined chassis. In North America and Australia this type of bus was introduced in the late 1940s as a replacement for unprofitable railway lines, while in Europe they have been around since the first buses.
The Ford 14-A was a prototype three-engined, large, streamlined, 32 passenger aircraft built in 1932. Though apparently completed, it never flew.
