Boeing 727 Cockpit
The 727 is the first airplane I remember taking when I was a kid. It was the best airplane ever (I recall the rear boarding/un-boarding ladder). You could smell the jet fuel and hear the hiss of the APU! I also had the opportunity to take the “other” tri-jet but from Tyполев: the TU-154.
I spent hours crawling over a QANTAS 747 ‘City of Launceston’ in 1980. Great fun.
