11 - I got the cesna wrong.
|
|
Sad to say I got all 12, although I got one from the text rather than the picture. Could even have told an A319 (one overwing door) from the A320 (two) in the picture. A330 from an A350 could have been trickier, though.

.....unless the A319 is operated by easyjet who have a bespoke config with 2 overwing exits (so they can get more seats in)

Similar exception with B757 v A321.
Diagnostic difference between them is the undercarriage. The 757 has a four wheel bogie on the main undercarriage whereas the A321 has twin wheels. Except the 321 was offered with a bogie undercarriage as a special feature. Only taken up by a couple of operators in Asia/far east though so not likely to be seen in Europe.

It was the A320 that was available with a 4 wheel bogie, but only fitted to aircraft for Indian airlines as they flew to some airports where pavement loading was an issue. Pretty sure it was never fitted to any A321's

Today's comic had a piece in the news pages on Richard Noble's jet powered LSR car. As usual the piece appeared to be by ignorant, illiterate foreign teenagers. Noble's car was variously described as a racing car and a racer.
The thing trundles around at low speeds up to 200mph on wheels with tyres. But for fast runs it uses solid forged aluminium wheels which will stay together at high rpm.
I think it just about reached the sound barrier on a previous run. Now the target is 1,000mph. Quite hairy for Noble and phenomenally pointless and expensive of course. But chapeau and yee-hah! all the same. I still remember Cobb's Railton-Mobil Special doing 401mph, and had a Dinky model of George Eyston's Thunderbolt among other LSR cars.

I suppose it will anyway, but Andy Green will be "driving" it. I can't say I know him well, but I have met him properly and he is a good guy, so I hope all goes well. I have no doubt it is properly dangerous.

>> I have no doubt it is properly dangerous.
Phew, you can say that again.
Of course Andy Green (sorry) will be driving a jet-powered trolley, not a car with driven wheels.
Cobb's Railton had two engines - were they RR Merlins? - inclined to fit into the tear-drop body and each driving one of the car's axles. Astonishing bit of Heath Robinson design really, but in the LSR tradition of course. What a lot of hassle though, harmonizing the two engines' crankshaft speed and torque output, with ever-present risk of a blip or sudden power loss at an awkward moment.
People can get killed stretching these extreme envelopes. They are crazed heroes.

Close, but no coconut:
The official land-speed record (measured over one mile) is 1,227.985 km/h (763.035 mi/h) (Mach 1.020), set by Andy Green (UK) on 15 October 1997 in the Black Rock Desert, Nevada, USA, in Thrust SSC.
Thrust SSC broke the sound barrier.
Bloodhound's designed to go even faster.
Tsk. Journalists.

But you aren't telling me anything I don't know bt.
There's a real difference between a car with driven wheels and a goddam rocket sled.
I love these cats, from Jenatzy onward. They laid their lives on the line. Malcolm Campbell tried again and again and his son Donald lost his life in a jet-propelled powerboat.

How about one driven by jet thrust?
Thrust SSC, or Thrust supersonic car, is a British jet-propelled car
Tsk. Ruddy journalists.

Careful with the 'journalists' chirps, sunshine!
Oh, Bloodhound runs on a jet, then a rocket from 450km/h. The rocket is fuelled by a perxide mixture pumped in by an F1 engine.
As far as the speed record goes, I interviewed Andy Green a few years back, and he was quite blase about it:
"The rules are simple, and will fit on an A4 sheet of paper. Must have at last 4 wheels, be steerable, cover a mile, turn round and come back within an hour.
Can run on nuclear reactors, or rubber bands."
Incredibly nice chap, and regaled us with stories of the JCB diesel car, which is an engioneering marvel in itself.

8 but, could have done better if I had done more than just glance at the pics.

More fun is the 'Cities from the Sky' (actually maps with the text removed) linked to on the plane quiz page.

11, got the Dreamliner wrong.
