These incredible designs were developed for aircraft that either never came to be, can’t yet be built, or don’t have any particular use.
But they do make for some fascinating photographs, illustrations and ideas.
Built in 1979, the NASA AD-1 proved that the wings of an aircraft could pivot quite dramatically without losing any of the planes’ stability.
The Stipa-Caproni was built in the 1930’s, with the propeller contained entirely within the fuselage. Although never put onto the production line, the aircraft worked and lead to the development of the jet engine.
The Nemuth Parasol was built by students of Miami University to prove that even a circular wing could keep an aircraft in flight.
The Vought V-173 was an experimental place developed by the US. It was able to fly exceptionally slowly.
The 281 Proteus was designed to be as efficient as possible in order to stay in the air as long as possible. This allowed the aircraft to act as telecommunication relays, though they later became obsolete with the development of unmanned aircraft.
The Blohm & Voss BV 141 was a German tactical aeroplane, notable for its asymmetry.
The Grumman X-29 was notable for its wings – which are attached to the body of the aircraft at the opposite angle to usual jet planes.
Designed for high speed, the Douglas XB-42 Mixmaster bomber placed propellers at the back of the plane to reduce drag effects.
The Sikorsky X-Wing aimed to combine the vertical lift of a helicopter with the forward speed of a jet plane. The project was dropped in 1988.
These blended wing planes where developed by Boeing, and were used to persuade NASA to arrange a contract with Boeing.
The Lockheed-Martin P-791 was designed to combine buoyancy with aerodynamic propulsion, allowing it to shift heavy cargo loads quickly.
The Russian Beriev Be-200 was a short-lived amphibious aircraft on a huge scale.
The White Knight Two is designed to carry spacecraft between the two fuselages and ferry them to the very edge of the Earth’s atmosphere.
The McDonnell XF-85 Goblin was a ‘parasite fighter’ that was meant to be deployed from the bomb bay of a larger plane.
Nasa’s Super Guppy plane was designed to haul oversized cargo.
The ‘Pregnant Guppy’ was the Super Guppy’s predecessor.
The hulking Bartini Beriev VVA-14 was a soviet plane that employed vertical take-off.
The Avro Canada VZ-9 Avrocar was developed by the US during the cold war in secrecy. The aircraft would have looked very much like a flying saucer, though it had severe overheating problems that prevented its practicality.
The Snecma Flying Coleoptere was a French experimental aircraft that could take of and land vertically, removing the need for a runway.
The De Lackner HZ-1 Aerocycle was designed to take a single soldier into difficult-to-reach areas for reconnaissance missions.
The Puffin was designed by Nasa to carry a single pilot.

Ball Court Cover at St Monica’s Catholic Primary School, Kangaroo Flat, Bendigo
Tucked away in the corner of St Monica’s Primary School in Kangaroo Flat is a big, impressive ball court arena.
The arena covers a bright basketball court – an excellently installed, impressive project.
Take a look at the photos below.

What Your Horse’s Sweat Patterns Mean
It can be hard to know if your saddle has been fitted well – your horse can’t tell you when something’s wrong, so you have to keep an eye out for some key indicators.
One way to do this is to look at the sweat and dirt marks left on your horse’s saddle pad.
By looking at these signs, you can get a sense of your saddle’s fit and what needs to be adjusted.
The two key concepts.
These are the most valuable things to remember when looking at sweat patterns:
- Sweat and dirt marks should be symmetrical.
Symmetry means that the saddle is sitting evenly on your horse. Sometimes non-symmetrical marks don’t indicate a bad fit and sometimes a problematic fit can still result in symmetry.
But as a general rule of thumb, this is a great one to go by.
- The centre line of you saddle pad (the gullet) should be dry.
Under no circumstances do you want the saddle to be rubbing or touching the spine of your horse.
How to interpret sweat and dirt patches.
Larger amounts of dirt and more darkness generally suggest that more rubbing is occurring in this area.
Ideally, rubbing is minimal and is spread out evenly.
Dirt at the front of the saddle pad means that the saddle is too wide and is being pushed forward.
Dirt at the back of the saddle pad could mean that the saddle is the wrong shape, or that the rider is sitting too far back in the saddle.
Diagonal dark patches indicate the points at which the saddle is swinging and rubbing. Diagonal points usually mean that the saddle will need to be custom adjusted to your horse.
Heaving rubbing on one side means the saddle is leaning to the opposite. In the diagram above, the saddle is leaning to the right.
This can also be caused by the way the horse is ridden, or the length of your stirrups.
Sweat and dirt patches are a rough guide. The most important step to getting a comfortable saddle fit is being attentive to your horse; their mood, their sensitivity and any tension in their muscles. Contact a saddle fitter if you suspect you aren’t able to get your saddle to fit nicely.
