The Cessna 172 started life as a tricycle landing gear variant of the [Vous devez être inscrit et connecté pour voir ce lien], with a basic level of standard equipment.
In January 1955 the company had flown an improved variant of the Cessna 170, a [Vous devez être inscrit et connecté pour voir ce lien] powered Cessna 170C with a larger elevator and more angular vertical tail.
[Vous devez être inscrit et connecté pour voir ce lien]
Although the variant was tested and certified, Cessna decided to modify it with a tricycle landing gear and the modified Cessna 170C flew again on 12 June 1955.
[Vous devez être inscrit et connecté pour voir ce lien]To reduce the time and cost of certification the type was added on to the Cessna 170 type certificate as the Model 172.
[Vous devez être inscrit et connecté pour voir ce lien] Later the 172 was given its own type certificate 3A12.

Early 172s were similar in appearance to the 170, with the same straight aft fuselage and tall gear legs, although the 172 had a straight vertical tail while the 170 had a rounded fin and rudder.
Later 172 versions incorporated revised landing gear and the sweptback tail which is still in use today.
The final aesthetic development in the mid-1960s, was a lowered rear deck that allowed an aft window.
Cessna advertised this added rear visibility as "[Vous devez être inscrit et connecté pour voir ce lien]" .

This airframe configuration has remained almost unchanged since then, except for updates in [Vous devez être inscrit et connecté pour voir ce lien] and [Vous devez être inscrit et connecté pour voir ce lien], including the [Vous devez être inscrit et connecté pour voir ce lien] in 2005.
Production had been halted in the mid-1980s, but was resumed in 1996 with the 160 hp (120 kW) Cessna 172R Skyhawk and was supplemented in 1998 by the 180 hp (135 kW) Cessna 172S Skyhawk SP.

Operational history
On December 4, 1958 Robert Timm and John Cook took off from McCarran Airfield, Las Vegas, NV in N9172B. Sixty four days, 22 hours, 19 minutes and 5 seconds later, they landed back at McCarran Airfield on February 4, 1959.
The flight was part of a fund raising effort for the [Vous devez être inscrit et connecté pour voir ce lien] Cancer Fund.
Food and water were transferred by matching speeds with a chase car on a straight stretch of road in the desert, and hoisting the supplies aboard with a rope and bucket.

Fuel was taken on by hoisting a hose from a fuel truck up to the aircraft, filling an auxiliary belly tank installed for the flight, pumping that fuel into the aircraft's regular tanks, and then filling the belly tank again.
The drivers steered while a second person matched speeds with the aircraft with his foot on the vehicle's accelerator
pedal.

Engine oil was added by means of a tube from the cabin that was fitted to pass through the firewall. Only the pilot's seat was installed.
The remaining space was used for a pad on which the relief pilot slept.
The right cabin door was replaced with an easy-opening, accordion-type door to allow supplies and fuel to be hoisted aboard.
Early in the flight, the engine driven electric generator failed.
