The dossier entry: El SAS y David Stirling
The Special Air Service (SAS) was founded in North Africa in 1941 by Scottish officer David Stirling, aiming to form small teams able to infiltrate behind enemy lines to sabotage Axis airfields and supply depots. Initially known as L Detachment, SAS Brigade, the unit grew into one of the most influential special forces of the Second World War.

Hyperbolic navigation via time-difference-of-arrival
Optical triangulation using stars
Inertial guidance via gyroscopes
Retransmission of enemy beacon signals
GEE was the first operationally used hyperbolic navigation system: it measured the time difference between pulses from a master station and several secondaries to plot hyperbolic curves whose intersection gave the position.
9 / 10
What visually distinguishes the Fw 190 from its squadron-mate, the Bf 109?
A short, rounded nose with a radial engine, instead of the Bf 109's long, narrow nose
A twin fuselage, similar to the American P-38 Lightning, instead of the Bf 109's single fuselage
An inverted gull wing, like the Vought F4U Corsair, instead of the Bf 109's straight wing
Fixed, spatted landing gear, like the Junkers Ju 87's, instead of the Bf 109's retractable gear
Its short, rounded nose with a radial engine and a large-diameter propeller clearly sets it apart from the Bf 109's long, narrow nose. It could carry up to 500 kg of bombs on strike missions.
