Harmer, Dalwick and Bojanowicz, with 1983 Diena certificate. This provisional was made by W.C. Campbell, the Secretary of the Postal Department. Stanley Gibbons states that 25 to 30 used examples are known. In 1919, the London "Daily Mail" offered a œ10,000 prize for the first non-stop flight over the Atlantic. The 1st plane, known as the Hawker, was forced down in the Ocean about 1,000 miles out. A second plane, the "Martinsyde" Raymor, piloted by Major F.P. Raynham and navigated by Major C.W.F. Morgan, also competed for the Daily Mail's prize. The crew arrived at St. John's on April 10, 1919 and made a valiant effort to assemble their plane in the shortest time possible. The first attempt was made on May 18, 1919. On takeoff the aircraft dipped in soft spot, the landing gear dug in and the aircraft hit the ground and was severely damaged. The navigator, Charles W.F. Morgan, sustained injuries that incapacitated him for a second attempt. The mail was eventually delivered by sea, cat. £30000 (Cat No. SG 142a) (Image)

1927 De Pinedo Overprint, 60c black, pos.12, well centered, n.h. and post office fresh, perfectly centered with wide margins all around, pencil signed Bolaffi, Diena, etc., v.f. example of this world-class rarity, with 2020 Philatelic Foundation certificate (this issue was intended for use on airmail flown aboard a plane piloted by Italian aviator Francesco de Pinedo. 300 stamps were overprinted, of which 230 were used on correspondence, 66 presented to De Pinedo and various dignitaries, and 4 damaged and destroyed. It is estimated that only 33 unused examples have survived to the present day. Francesco De Pinedo (1890-1933) was a famous Italian aviator of the time. By 1927, he had flown most of the globe in his double-hulled Savoia-Marchetti seaplane named the "Santa Maria II". In May 1927, De Pinedo was on the last leg of his circumnavigation of the Atlantic. The Newfoundland government asked him to carry a mail bag back to Italy for them. He agreed, and the stamp shown above was quickly issued to publicize the event. He took off from Trepassey, Newfoundland on May 23, 1927. During his flight from Newfoundland to Italy, De Pinedo experienced engine trouble and he was forced to land in the ocean. He and his aircraft were found, and they were towed to the Azores. Following repairs to his aircraft, De Pinedo finally completed his flight, and he arrived in Rome on June 1, 1927), cat. $100000 (Cat No. C4) (Image)
