Concord came to Anchorage in July, 1988 for a promotional tour and flew customers Mach 2.0, 65,000 feet and half way to Hawaii and back in two hours for $1,000.
I got my nerd on and went to Point Waronzof and took a video and had a decibel meter to record the moment. I'm thinking 122 or 127db I read. Not a big aircraft.
It was there for a couple days and I found it parked nose bent down right in front of of a tall chain link fence which I had access to from the outside.
This is where I stood as it came down the main runway they are expanding in this photo. I spent a lot of time there across the years I lived there as 747's took off all the time. They can make it all the way from Europe without refueling now to the contiguous US. I think that has been for a long time. 25+ years.
This is cool.....
