The SAAB JAS 39 (Grippen) is a Mach 2 single-seat, single-engine multi-role: air-to-air, air-to-surface, and recon aircraft in service since 1996.

Dark matter neither reflects nor emits light, yet it binds galaxies together and might constitute about 80% of the universe's mass. Similarly, dark energy could account for the faster-than-expected expansion of the universe. The Euclid aims to map this "dark universe".

"Black shoes" denote the ship's permanent crew, while "brown shoes" refer to pilots visiting temporarily before returning to land post-deployment. Despite a subtle rivalry and varying traditions and uniforms, both groups share the overarching goal of safely launching and recovering aircraft.

The F-35 has six distinct mission sets, making it the world's most capable multi-role fighter aircraft.

The BRICS nations (Brazil, Russia, India, China, South Africa) aim to challenge the US dollar's global dominance, yet their economic influence is limited.

An Icelandic firm, deCODE, employs artificial intelligence to correlate genetic data with intricate details of an individual's lifestyle such as diet, personality, relationship preferences, hobbies, and causes of death, aiming to discover statistically significant associations that could be of scientific interest.

The capability to rapidly construct ships was crucial in the triumph of the USA and the Allies over Japan, Italy, and Germany during World War II. The US didn't solely manufacture ships for its use, but it also provided for its allies.

The X-65 demonstrator drone, an "experimental uncrewed aircraft," will employ compressed air nozzles for maneuvering instead of traditional control surfaces like flaps, rudders, and spoilers. This nozzle-based system aims to reduce weight, fuel consumption, and complexity while also improving aerodynamic geometry for lower radar signatures.
