FEBRUARY 8TH, T945 147 CARGO AIRCRAFT the order of Guinea Airways, Ltd., around 1929. They were in service in New Guinea until the Japanese invasion. .^•cess to the cargo hold is through a very big hatch in the roof as well as through side doors. It makes a fine cargo aircraft. The G31 is a typical Junkers low-wing monoplane, all-metal and rugged, powered with- three B.M.W. Hornets of 575 h.p. each. Its all-up weight is 18,750 lb. ; disposable load, 8,150 lb. ; and maximum pay- load over the very short Lae-Bulolo Service, 7,300 lb..The cargo compartment measures 25ft. long, 6ft. 5m. wide and 5ft. o.in. high. The detachable hatch on top is 11ft. ioin. in lengthX5ft. wide. This hatch is provided with a domed cover to give an additional I2in. of headroom below the hatchway and directly over the centre of gravity of the loaded machine, where, of course, the largest pieces are carried. Its cruising speed is about 105 m.p.h. In comparing the above figures with the Bristol 170 it should be remembered that we now have a totally different conception of what is meant by cruising horse-power. The 170 is designed to cruise on only 42 per cent, of its maxi- mum horse-power, whereas the G.31 uses about 80 per cent. Another freighter was the 750 h.p. single Cyclone-engined XC-31 Fairchild produced around i<»4 for the U.S.A. Army.

The Curtiss Caravan freighter has apparently been abandoned. It was designed during the war for wooden construction with the intention of i.sinjj non-strategic materials and plant capacity. During the development period the supply position as regards light alloys hi relation to spruce and plywood became reversed. Perhaps our wooden gliders and Mosquitoes had something to do with that! Finally, the American Budd Company have recently pro- duced a prototype freighter in stainless steel, using their own system of shot welding. Billingsgate Beaten Horace says ... In contemplating freight carrying we like to recall that fresh fish delivery in the early 16th century over those 200 miles from the warm waters of the Caribbean to the palace of the Aztec Emperor Montezuma on the 7,000ft. uplands near Mexico City. It w;is a relay race against the clock and Isaac Newton. Hundreds of sprinters were stationed at intervals all along that mountainous track and each tried his best to beat even time. Their motto was "The Fish Must Get Through." As a result fish caught in the evening in the Mexican Gulf was on the Emperor's gold breakfast plate the next morning. Of ;course, being an Emperor he might have been one for a late breakfast! He was certainly one for a bit of fried fish 1 Relays of horsemen could have made better time and Ihey could have carried a bigger pay load,' but the Only living horses in Mexico at that time were those brought by Cortes the Conquis- tador. What Montezuma really wanted was a freight aircraft, and had he known it there was ample petrol and oil down at Vera Cruz! That same primitive form of freight transport is still in use in many parts of the world. Loads are still carried by human pack animals. There are pack horses, mules and donkeys in many coun- tries ; reindeer in Finmark ; camels in Africa ; dog-teams in North America ; yaks in Thibet; bullocks and buffa- loes in the Far East; llamas in Peru ; elephants in Siam. Some of those camel teams travel hundreds, indeed VENTRAL ENTRY : A " duck " and an ambulance drive up the loading ramp of the Budd shot-welded Conestoga freighter.
