HP.115, Slender Delta That Proved Concorde’s Wing

HP.115, Slender Delta That Proved Concorde’s Wing

It looks like a paper dart that a child drew and an engineer took seriously. A long needle nose, a huge triangular wing, spindly stalk-like landing gear, and a single small jet perched at the base of the fin. The Handley Page HP.115 was one of the strangest and most...
Kaman K-MAX, Synchropter That Outlifts Itself

Kaman K-MAX, Synchropter That Outlifts Itself

Watch a K-MAX work a mountainside and something looks wrong. Two rotor masts lean apart in a shallow V, their blades slicing through each other’s arc, and yet nothing collides. There is no tail rotor at all. This is the Kaman K-MAX, a synchropter built for one...

Be-200 Altair, Russia’s Amphibious Water Bomber

A wall of orange climbs a Greek hillside, and out of the smoke drops a white-and-blue jet skimming the sea. It touches the waves, drinks twelve tonnes of water in fourteen seconds, hauls itself back into the sky and unloads the lot onto the flames. This is the Beriev...

Lockheed’s 240 mph Gunship the Army Feared

Lockheed’s 240 mph Gunship the Army Feared

At an airshow in December 1967, the Lockheed AH-56 Cheyenne did something helicopters were not supposed to do. It bowed. Landing on its two forward wheels, it dipped its nose to the crowd, then gently set its tail down and taxied away. The trick was the pusher...
Scimitar: Royal Navy’s Swept-Wing Bruiser

Scimitar: Royal Navy’s Swept-Wing Bruiser

When the Supermarine Scimitar first crashed onto a carrier deck in 1958, it arrived as the biggest, heaviest and most powerful aircraft the Fleet Air Arm had ever tried to operate from a ship. Twin Rolls-Royce Avons gave it such brutal thrust that a pilot could stand...
