ITALY'S HEIGHT RECORD
Caproni 161 with Two-row Piaggio Reaches 51,348 ft.
ITALY'S recapture of the altitude record proves once again the worth of the method used by that country of training pilots in special schools for special purposes. The world's speed record, still unbeaten, was established at the school in Desenzano, where regular high-speed experiments and classes are held each year. The long-distance navigation school at Orbetello proved equally successful by organising the two mass flights of Marshal Balbo and his squadron across the South and North Atlantic. For the most part the credit for breaking the world's altitude record is due to the high-altitude school at Guidonia.
The new world's height record of 51,348 ft. was established on May 7 by Lt.-Col. Mario Pezzi, who commands the Guidonia school, on a Caproni 161 single-engined biplane powered by a Piaggio P.XI R.C.73 fourteen-cylinder double-row radial. The previous record held by Sqn. Ldr. Swain in the Bristol 138 monoplane has thus been beaten by 1,417 ft.
In the Caproni 161, the cockpit is open, but the pilot wears a special airtight electrically heated suit made of rubber and fabric, reinforced with light alloy sheets. His head is enclosed in a large light-alloy cylinder with heated glass windows.
The 161 is derived from the Caproni 113 which held the world's altitude record previous to Sqn. Ldr. Swain's effort on the Bristol. The biplane arrangement was chosen because of its light structure weight. It is claimed that the machine has a safety factor of well over six, can perform aerobatics and fly inverted. The fuselage and tail unit are of steel tubular construction, but the wings are of wood, the whole machine being fabric covered. The Piaggio XI R.C.72 delivers 710 h.p. at 23,600ft., and 140 h.p. at 46,000ft. It is fitted with a down-draught carburettor and automatic mixture control. For the record attempt the compression ratio was increased so that the theoretical power at ground level was more than 1,800 h.p.

Мировая Авиация 102
1934 год - 14433 м. Коммандер Ренато Донати, вылетев 11 апреля 1934 года из Рима на Caproni Ca 161, установил новый мировой рекорд высоты. В конце 1930-х годов на таком самолете подполковник М. Пецци еще дважды бил мировые рекорды высоты. В 1938 году на Ca 161 bis (на фото) он набрал высоту 17 069 м - последний официальный мировой рекорд высоты, установленный на самолете с поршневым мотором.
The Caproni 161 which was specially designed to attempt the world altitude record which it broke in May 1937.
Het Vliegveld: 09.05.37: A new altitude record of 15,655m is established by Mario Pezzi in a Caproni 161.
Het Vliegveld: 09.05.37: The new altitude record of 15,655m (51,362 ft) was established by Lt Col Mario Pezzi in a Caproni 161 bis at Montecelio, Italy on 08.05.37 although Italian publicity photos quote 07th. The aircraft was specially designed for the task, having been developed as the Ca 161 in 1934 from the Caproni 113 aerobatic biplane with a wing span increased from 34 ft 5 in to 46 ft 9 in. On 11.04.34 it set a new record at 14,432 m (47,352 ft) fitted with a licence-built 700 hp Pegasus and flown by Cdr R Donati. For Pezzi's record it was fitted with a 1,000 hp Piaggio PXI.RC.100 14-cyl 2-row radial fitted with a 4-blade propeller. Unfortunately before the record could be officially recognised by the FAI it was beaten by Flt/Lt M J Adam on 30.6.37 when he reached 16,440 m (54,056 ft) in Bristol 138A K8479. Pezzi raised the record further on 22.10.38 when he achieved 17,082 m (56,046 ft), a piston engine record which still stands. -

RECORD BREAKERS ON SHOW: Among the exhibits at the Milan International Aircraft Exhibition, which opened on October 12, are the Macchi-Castoldi which did 440.67 m.p.h., the Cant. 501 seaplane which recently flew 3,104 miles non-stop, and what appears to be a two-seater version of the Caproni biplane which holds the altitude record. The monoplane in the background is the new Potez light transport.

The pilots of the RAQ pose beside the Caproni Ca.161. Capitano Aldo Oddono, second from left, was the only pilot to fly the AQV. Other members of the group include Maggiore Tomaso Lomonaco, the doctor who oversaw the physiological aspects of the high-altitude programme (third from left) and pilots Tenente Colonello Mario Pezzi (second from right) and Maggiore Nicola Di Mauro (furthest right).
