Nice pictures.
I’ve not been on the Waverley, but we we did the trip on the Balmoral a few years ago.
It’s a whole different experience seeing London from the Thames. We went to and from Southend pier, which was
a four hour trip each way.
Looking at your pictures, the boat looks packed to capacity, very much as ours was.

The owner paid for it and it’s his business as to what it cost him, isn’t it?

I expect it is the business of Mark One Partners LLC. Although they did quote some of the costs involved.
I see they also own another Mk.1 P9374

Plenty here about who was involved.

I enjoyed it. Rather different to the usual “Spitfire” documentary.

I see that Andy Saunders was one of the consultants.

I also took a photo of this one, no idea what it is though.

Not a display of fire bombing at an airshow, but I’m sure there was a display by an Air Atlantique DC-3, spraying water
at an airshow. I don’t remember where or when though.

I think I must have left before it flew 🙁

Came down close to a school…. or so report says – but no mention of a brave pilot fighting his crippled jet to avoid the school (so far!) .

Although in the BBC News report, they did say (three times), that it was a Primary school.

I did wonder (for a moment) as to why both seats would fire when the pilot ejects. Not much point staying with the aircraft once the pilot has gone though.
