You can fly into Brunters on the fast taxi days. Went last year, taxiways not in brill condition so keep the speed down but great day out. Think the next one is in May sometime.
If area rule was good why would it fall out of fashion?
The suggestion in the article is that it hasn't gone away, but is achieved by more discrete means than fuselage shaping.
I'm not an aircraft designer so there my ability to comment ends, apart from being introduced to the concept by the lovely waisted fuselage of the F5.

There are rules and then there is how you apply them...
Cessna hired the discoverer of the Area Rule Richard Whitcomb to work on their Citation X. Very strange shapes resulted but it's very fast.
Trouble is the results appear counter-intuitive. Kingston area ruled a single seat Hunter but you could barely see it and it made no difference. When they made the 2 seater it was faster than the single seater with a less powerful engine.
The Bucc was good with a profile drag coefficient around half the typical value and they reckoned it wasn't quite right and could have been lower. But you have to do a few unfashionable thing like faired in drop tanks, T tail, internal bomb bay etc to get the lowest drag.
Today in Mil FJ the attention is paid to the boxes, not the aerodynamics though they have little effect on your range and speed.

As I remember the T4 and T5 Frighting were faster than the single seaters because of the bulge at the front to fit the two seats in. Altered the area rule thingy apparently.

Not that fast taxi day then?

you knows what I means...Departure instructions on the day...we went before the thundering up and down the runway had finished 'Oh just take off on the taxiway, keep to the right hand side though or your wheels will come off'....

Yes, there is the engineless one painted in bright Green, it is currently being worked on and a search is on the go for parts to get it back to running condition, needs a couple of engines amongst other things, they could upgrade it and buy a couple of leafblowers off the Shopping Channel. 
Most of the ones not bought from the RAF are training aids at Cosford for the Sprog Engineers, several do taxying but have had the reheat baulked I believe, there is also a bunch of taxying examples at Cranwell to train Sprog Eng O's
The others that were sold are at Bentwaters and for sale, google Everrett Aero.
Indeed the RAF finding they were short of a runner had the ignominy of having to buy one back.
Corrected post to read Cranwell, slight brain dump.

The Germans used the Area Rule on some of their advanced aircraft towards the end of WW2, so I don't think Whitcomb discovered it.
Maybe Hollywood are planning a film..

The only aircraft designed with reheat that do fast taxy runs at Brunty (to my knowledge) are the Frightnings and they definitely use it on their runs.
Not for very long though!

An interesting video from Bruntingthorpe
. I know the 1198 has been superceded by the 1199, and there's also BMW's S1000R now, but it's still entertaining, and shows the difference between cars and bikes.
