It is very easy to recognise a B-52. The eight jet engines, mounted in pairs under the wings, and the four main landing gears under the fuselage make it stand out from all other aircraft.
Boeing C-97 Stratofreighter & 377 Stratocruiser
Few piston engined transport aircraft can be recognised so easily as the Boeing Stratofreighter/Stratocruiser. The double-bubble, eight-shaped fuselage and the blunt nose with many cockpit windows are a unique sight.
Like the Antonov An-72 the YC-14 STOL jet transport has engines in the wings' leading edges, blowing over the wings to increase the lift. The nose has a similar shape as the Lockheed Hercules, although with less cockpit windows. Only two were built.
Compared to the Boeing 737 and Airbus A319/A320 the CSeries aircraft have a very streamlined nose, including the cockpit windows. Also apparant for the CSeries are the winglets, attached at 45 degrees with respect to the wings. The similarly-sized Embraer 190/195 and Mitsubishi Regional Jet have a slimmer fuselage. Finally the CSeries have a squared off tailcone, which the others don't have.
The Global series of large cabin business jets built by Bombardier are clearly a derivative of the Challenger series and Regional Jet series 100/200. This is especially visible when looking are the front of the fuselage as the cockpit windows and cabin windows are the same. However, the Globals have a different tail and engines with a single exhaust.
Boom Supersonic XB-1
The XB-1 acts as demonstrator for a supersonic airliner. It has delta wings, a triangular tail and three engines. Two engines are under the wings, next to the fuselage, and one is in the rear fuselage. All air intakes have a wedge shape and the inlet of the middle engine is on top of the fuselage, in front of the tail. (photo Boom Supersonic)
Breguet Br1150 Atlantic
This purpose-built maratime patrol aircraft is easily recognisable by its double-bouble fuselage, meaning an eight-shaped fuselage cross section. Other characteristics are the glass nose, MAD antenna extending from the tail cone and long, slender engine nacelles.
Bristol 170 Freighter
Designed specifically to transport cars across the Channel, the Bristol 170 Freighter has clamshell doors in the nose to facilitate loading. The cockpit is above the cargo bay, giving it a rather fat appearance at the front. This makes for an easily recognisable prop aircraft with a fixed, tail-wheel landing gear.
The British Aerospace 146 is a four engined medium size jet airliner, of which most versions are passenger aircraft with cabin windows. That latter makes it stand out compared to other aircraft in this category. The cargo versions of this BAe146 are also recognisable because of the relatively small size and the speed brake in the tailcone.
In an attempt to modernize the Hawker-Siddeley 748 and capture a part of the booming commuter market British Aerospace basically stretched the HS748 and fitted the aicraft with modern turboprop engines, driving six-bladed propellers. The Advanced Turbo Prop (ATP) was born.
