That was the science round.
This was the 6th-easiest round of the season, probably because
it included too many hints.

Was Stephen's answer "j" a typo? The natural horn doesn't come

And now you know where Brooke McEldowney got the name for his

(High-bypass) turbofans. The compressor is enlarged into (or
augmented with) a "fan", so that some air from the intake is blown
directly into the exhaust, bypassing the combustion chamber. This air
provides a majority of the thrust; in effect the fan is doubling
as a propeller. (Any short answer along these lines or mentioning
"fan" or "bypass" was fine.) 4 for Dan Tilque, Stephen, and Dan Blum.

The crankshaft stood still and the cylinders rotated around it as a
unit, attached directly to the propeller. (Anything close was okay.)
4 for Stephen.
The main advantage of the rotary was that the cylinders moved
through the air so fast they needed no other form of cooling.
One disadvantage was lubricant dripping continuously off the rim of
the engine -- with consequent, ah, biological effects on the pilot,
since the usual lubricant was castor oil!
Another notable quirk was that the gyroscopic effect of the large
rotating mass made it easier to turn the plane to one side than to
the other -- which pilots in dogfights had to allow for.

(Douglas) DC-3. Its military names, the Dakota and the C-47 Skytrain,
were also acceptable. 4 for Bruce, Dan Tilque, Stephen, and Dan Blum.

(De Havilland) Comet (1), (Avro) (C-102) Jetliner. 4 for Bruce,
Dan Tilque, and Stephen.
The Comet 1's design flaw was rectangular windows. Metal fatigue in
the pressure hull focused on the sharp corners and led to explosive
decompression after less than two years of flying.

Canard. 4 for Bruce, Dan Tilque, and Stephen.
So named from its resemblance, together with the structure linking
it to the main part of the plane, to the head and neck of a duck.

Skunk Works (from "Pogo"); Lockheed. 4 for Bruce, Dan Tilque,
Stephen (the hard way), and Dan Blum.
