An aviation related A Level Physics question; you have 40 minutes to answer. (Some data / constants had been given on the front of the paper).

(e) repeats the nonsense that the air above the wing is forced to flow faster. It isn't, it is a fluid, not a solid, and is independent of the air below the wing.

@Colonel Panic is this all the result of the anti-hoarding treatment working?

that quote reminded me of Flanders & Swann's 'Friendly duet', written during the 'Profumo Affair':

https://www.musixmatch.com/lyrics/Fland ... endly-Duet

.. which ends:

"So guard against gossip, and take every care
Lest some blameless escutcheon you blot;
Such models of friendship are precious and rare
Though the friendship of models is not!"

Hoarding is not when of my better traits. Not helped by the fact that I have not moved house in 30 years.

I have come across two Faversham Bank One Pound Notes. One is dated 1810, the other 1811. Incredibly delicate "paper" ...

I also have a collection of ALL of the Bank Cards that I have ever had - ranging from £10 Cheque Guarantee Cards through to modern day.

@Colonel Panic I confess a degree of fellowship, mostly in ancient paperwork and obsolete mobile phones, ipads and PC cables and accessories.....

We moved house 15 years ago which did help a bit.....

The RN dabbled in fluidics in the mid ‘60s as a control mechanism which would be incorruptible by electromagnetic influences. Thank goodness it never came to pass as I just couldn’t get my head around it.

Nothing wrong with hoarding stuff. My wife occasionally insists on a clear out of my garage or my shed after she has been unable to locate something or other that she wanted. I reluctantly comply, shedding as little as I can get away with while maintaining domestic harmony, but I guarantee that within a week I will have need of something that was hoarded for years unused and which went in the clearout. It is so infallible that there should be a name for the law that dictates that should happen.

There is: "CherokeePete's Law" (TM).

Founded on the basis that 5 mins after I post something it will be deleted then someone will wish it was still there because it was extremely useful.

As an amusing aside, here is my journal entry for the exam day itself (followed in short order by a Genesis concert & a Ted Nugent album). #showingmyage

Sadly private schooling didn't seem to do much for my use of colloquial language ...

And why paper aeroplanes fly.......
