The Boeing 314 Clipper Flying Boat, 1938.

image002When the Boeing 314 flying boat made its appearance, it was the largest civil aircraft in service. 
The Yankee Clipper project dates back to 1935, with the start of a series of negotiations between Pan American World Airways and Boeing for the production of a flying-boat capable of guaranteeing transatlantic passenger flights with a high degree of safety, comfort and speed.
On July 21, 1936, Pan American signed a contract for six Model 314s, the first of which made its initial sea run on Puget Sound on May 31, 1938, and made its inaugural flight on June 7, 1938.
It outstripped all rivals in size, with twice the size of the Sikorsky S-42 and outweighed the Martin M-130 China Clipper by 15 tons. The 14-cylinder double-row Wright Cyclones were the first to use 100-octane fuel.
The Boeing 314 weighed 40 tons and the first block ordered cost $550,000 per aircraft.

It had a central hull and adopted the wing and engine assembly of the experimental Boeing XB-15 heavy bomber.
In the place of the traditional floating stabilizers at the wingtips, sponsons (flotation device)  mounted on the sides of the hull were used.
The sponsons were based on the formula developed by the German engineer Claude Dornier and incorporated into such aircraft as the Dornier Do X and Dornier Do 18.
The sponsons (flotation device) also contained fuel tanks, the capacity of which (together with those situated in the wings) totaled almost 3,525 gallons (16,000 liters).

This was First Class Air Travel in the 1930s.

Flying was very expensive. Most people still rode trains or buses for intercity travel.
Only business travellers and the wealthy could afford to fly. America’s airline industry expanded rapidly, from carrying only 6,000 passengers in 1930 to more than 450,000 by 1934, to 1.2 million by 1938.
Still, only a tiny fraction of the travelling public flew.
The very first aircraft were narrow and long, and the passenger seats were perceived as an innovation, a kind of luxury and an optional extra, like caviar sandwiches with butter.
The first seats were the most common chairs, seat belts were not.
At first, the passengers were sitting right behind the pilot, there was no partitions.

“Flying Machines.”

agdag-3If you want to create detailed and imaginative flying machine sculptures that look like they’re about to take flight, cardboard is hardly the material to use.
Unless of course you’re artist Daniel Agdag, who has been toiling away creating a series of new works each more detailed and fascinating than the next.
“The Principles of Aerodynamics” is Agdag’s first solo exhibition where his series of cardboard contraptions that portray his “ongoing pursuit of escape through the metaphor of flight” will be on display.
As he’s done in the past, Agdag forfeits all blueprints, drawings and plans choosing, instead, to work only from mind and scalpel.
His industrial beasts–get close and you can almost smell the oil and smoke; hear the clanking and buzzing–come together only from sliced cardboard hinged with glue.
