Cessna 172 Skyhawk

The Cessna 172 Skyhawk is a four-seat, single-engine, high-wing, fixed-wing, aircraft made by the Cessna Aircraft Company.
First flown in 1955, more Cessna 172s, and it's variants, have been built than any other aircraft.
Many pilots obtained their pilot's license learning to fly the 172.
A 1958 Cessna 172 was used to set the world record for flight endurance and that record still stands today.
Around 60,000 Cessna 172,'s have been built and it is the most successful aircraft in history.
It's uncertain how many are still airworthy and flying today but the number is in the thousands.
