Aermacchi AL-60

The Aermacchi AL-60 is a light civil utility aircraft of the late 1950s and early 1960s, originally designed by Al Mooney of Lockheed in the United States. After the company decided not to build the aircraft in the US, it was manufactured in small quantities in Mexico, and a few were assembled in Argentina (Santa Isabel, Córdoba, by Aviones Lockheed-Kaiser Argentina. It was also built in quantity under licence by Aermacchi in Italy[2] and Atlas Aircraft Corporation in South Africa.

Design and development

Lockheed flew only two prototypes of the AL-60 (in 1959) before deciding that it would be unprofitable in the US marketplace. Instead, the company chose to manufacture it under a joint venture in Mexico as Lockheed-Azcarate (LASA). 18 were produced in 1960 for the Mexican Air Force, as the LASA-60.

In Italy, Aermacchi purchased a licence to produce the type, first in its original configuration as the AL-60B, then in a modified version for various African customers as the AL-60C. This latter version changed from the original tricycle undercarriage to a taildragger arrangement.

The AL-60C version was built under license by Atlas Aircraft Corporation in South Africa. This aircraft was known as Atlas C4M Kudu. Over 40 aircraft were built and served the South African Air Force between 1974 and 1991.

A number of C4M Kudu aircraft are still flying privately and have proven well in the role of skydive release aircraft. They have been re-engined with turbine engines. This design is known as the Atlas Angel or Turbine Kudu.[3][4][5]

In 1968 Macchi sold the rights to the aircraft to Northwest Industries of Edmonton, Alberta, Canada and the design was developed into the Northwest Ranger, with development continuing until 1972.[6]

gollark: You can get bigger individual sticks though.
gollark: Up to a point; there are only so many slots available and if you fill *all* of them it might drop into a slower mode.
gollark: That is RAM which exists, yes. Probably.
gollark: RAM is a bunch of small PCBs which go onto the slots on the motherboard.
gollark: For somewhat complicated technical reasons, it's not really possible to split gaming tasks onto two. You can do it fine for some general purpose computing ones however.
