The miniaturised instrumentation left an impression with me. Further, it looked like every part on the interior of the aircraft had been uniquely customised, shrunk and lightened; the design cost must have been staggering.

The initial development estimate for Concorde was $130 million. However, this was vastly exceeded by the final cost reaching over $2.8 billion. In the 1960/70-ies, mind you. Today, it would have been $23.5 billion... Each of the British and French governments funded $1.44 billion. These costs were mostly written off and never recovered. Only twenty of the estimated 350 aircraft were ever built. 

I had seen this aircraft before, I happened to be transiting at Heathrow when it took off for one of its final commercial flights in October 2003.  There is one other personal connection: Patricia's father and uncle were on the design team of its Olympus engines.

Interesting difference in the principle of the engines. The Pratt and Whitney used a cone structure to deflect the intake airstream into the afterburners to create a ramjet effect at supersonic speeds whereas Rolls Royce had a three-flap system to slow the intake airflow down to subsonic speeds.

Forgot to edit in that the engine shot was M240-P + 50 Lux ASPH.

Had the chance to spend a day via the Bristol Owners club where we combined Filton and Yeovilton so visited the prototype and last example (AFAIK) in the same day, with a talk from a pilot involved in the development/testing.

It was interesting to hear about the changes from the prototype including the lengthening of the body to accommodate enough seats to make it commercially viable and the subsequent changes to the geometry of the wings. I might be mis-remembering but I believe it was the only non-military aircraft sanctioned to use afterburners on takeoff in the UK

Yeovilton? 

No; Brooklands.

Probably better known as a motor museum but IIRC it started life as an airfield during WW-1 (with aircraft manufacturers located on site?) and has a few choice aircraft on display such as Concorde G-BBDG and a VC10.

Today the place is hosting a motorsport day and I'm having a wonderful time.

Earlier on the cars drove through the paddock to an adjacent track and in 20 mins or so the cars will be tackling the 'Test Hill'. Back in the day if a car could crest the summit it was deemed 'fit to race'.

I have selected my vantage point 95% up the slope...

P.

EDIT : Apologies for the Time-Frame Delay! This post was typed at 12:40 but for some reason didn't upload until 18:25! Almost certainly 'User Error' but don't ask me "Why?"......

I have yet to visit the one at Filton.  Have seen, climbed through 2, possibly 3 others.

It is in a beautiful condition and impressively displayed. The rest of the museum well worth a visit too. I looked at the Red Arrows experience and decided that it would likely lose me my breakfast.

I was on a coach on the M25 going to Heathrow as Concord took off over us, and the sight of her four engines glowing bright red is a memory for life, plus of course the noise!

We are on a (very high) Heathrow flight path, and around the same time every evening the windows would rattle a little as she flew over.
