Swallow New Swallow

(Redirected from Swallow Mailplane)

The Swallow New Swallow, also known as the Swallow Commercial Three-Seater[2] is an American-built general purpose biplane of the mid- to late 1920s. The New Swallow name was to distinguish it from the aircraft from which it was derived, the Laird Swallow.[3][note 1]

Development

edit

The Swallow Airplane Manufacturing Co was formed in 1923 to take over the business of the E.M. Laird Aviation Co. of Wichita, Kansas and set up its factory there. In 1924, the New Swallow three-seat biplane was introduced, which differed from the earlier Laird-Swallow in having a cowled engine, split axle undercarriage and single-bay wings.[4] About 50 examples were produced until the design was enhanced in 1926. The initial price was $3,500 reducing to $2,485 in late 1926.

After 1926, production shifted to the redesigned, steel-framed Super Swallow.[1]

Operational history

edit

The three-seat Swallow found ready use in the hands of small commercial firms and with the newly founded regional airlines.

When the Air Mail Act of 1925 came into force, Walter Varney tendered for route CAM 5,[5][6] which connected Pasco, Washington with Elko, Nevada via Boise, Idaho,[6][7] crossing the Cascade Mountains.[6][8] He won the tender unopposed,[6][7][8] and ordered six New Swallows to service the route.[5][6][7] These aircraft, sometimes known as the Swallow Mailplane[5][7] differed from the current production version by being equipped with a 160-hp (119-kW) Curtiss C-6 water-cooled, inline engine.[5][7] Their wingspan was extended by four feet (1.2 metres) and the passenger cockpit was enclosed to create a hold for mail.[7] The first flight took off from Pasco on April 6, 1926.[6][7][8] Pilot Leon Cuddeback[7] transported 9,285 pieces of mail, weighing 207 pounds (93.9 kg), plus bottles of grape juice intended for President Calvin Coolidge.[8] Cuddeback also completed the return trip successfully, but the following week,[6] on the second flight out of Pasco, was forced down in the desert.[7] The Curtiss engines proved unsuitable for the hot-and-high conditions,[8] and Varney ordered replacement air-cooled 208-hp (155-kW) Wright J-4s instead.[5][6][7][8] After 60 days grounded,[6][7] the re-engined Swallows returned to service.[5][6][7]

Three Swallows participated in the 1925 Ford Air Tour, piloted by Earl Roland, John Stauffer, and Jacob Moellendick.[9]
