Boeing 747 Jumbo Jet

I was still in London in January 1970 when the first Jumbo Jets went into service with Pan Am. I was standing on the Thames Embankment when one circled overhead on its approach to Heathrow. It looked immense; of course, it was!
Throughout the Seventies, as a bachelor with no mortgage or home-ownership items to spend my pay on and saving for retirement had not clicked-on in my brain, I spent my dollars on travel. Not bucket-list safari stuff but seeing family in 3 countries and friends on 3 continents.
Pretty soon I had flown on many Jumbos.
Those were interesting flights. You could ask for "upgrades" to First Class, and if there were a lot of those seats available, they would give them to you at no cost. Obviously, it was a teaser to encourage one to promote those extras that one received.
What I remember most, and fondly because I cannot imagine it happening now on commercial flights, was the bar where you could stand and drink your Johnny Walker Red with 2 ice cubes only!!

Yes, there was a spiral staircase that took you up to the hump on the top of the plane where the seats were more like a lounge than the usual rows of seats.

The lounge shown in the above picture was not the one I sat in but the only one I could find on the Internet at the moment. The comfy seat I had, was arranged more like a small room or the ones we see nowadays on private business jets.
I flew one time in a 747 First Class that was configured such that my seat was right in the front nose cone with a window directly in front of me. It was an awesome journey through the clouds!
