Learjet 23
The Learjet 23 was first introduced in 1964 and was originally supposed to be used as a ground attack fighter for the Swiss Air Force. Though it didn’t work out, this airplane didn’t go to waste. Bill Lear adapted the design into an executive jet that could reach potential fighter-like performances, like taking passengers to their destination at 540 miles per hour.
Cessna 172 Skyhawk
The Cessna 172 Skyhawk is actually the best-selling plane of all time and has sold over 44,000 of them. Because of its popularity, the Cessna 172 is now being used as the universal training aircraft for militaries. It flew for the first time in 1955 and, though still in production today, has an upgraded version to meet modern technological needs.
