The global aviation community was stunned. The Americans who built the plane were left speechless. Indian engineers & a fearless pilot had taken a foreign cargo plane, bolted a fighter engine to its roof & rewritten the rules of physics in the sky.
It is July 23, 1962. The jagged, barren wasteland of the Karakoram Range looks like the surface of the moon. In the valley below, a crude, unpaved strip of dirt & loose gravel sits frozen in the Karakoram Pass. This is Daulat Beg Oldie (DBO): the highest advanced landing ground on Earth.
Tensions with China are simmering to a boil. The Indian Army jawans stationed on this freezing frontier are completely cut off. They need men, they need ammunition & they need them yesterday. But conventional military wisdom says flying a massive, heavy transport plane into DBO is a suicide mission.
The air is too thin to create lift. The dirt strip is too short to stop.
The Western aviation world had already given its verdict: Impossible. They did not account for Indian ingenuity & they certainly did not account for Squadron Leader C.K.S. Raje.
On the tarmac at Jammu, a twin-boom Fairchild C-119G Packet transport plane affectionately known as the "Flying Boxcar" idles. But this is not a standard American-built cargo plane anymore. Perched precariously on top of its fuselage, like a rocket backpack, is a raw, unshielded British-designed Orpheus 701 jet engine, ripped straight out of a Folland Gnat fighter jet.
This mechanical chimera is the brainchild of Indian maintenance engineers & the fledgling GTRE. It is an unproven, terrifying gamble. If the jet engine fails/if its immense thrust rips the roof off the fuselage, the plane will disintegrate. Climbing into the cockpit is Squadron Leader Raje. Walking in right behind him are 32 battle-ready jawans loaded with full gear & Air Vice Marshal Erlic Pinto, the chief of Western Air Command, who refuses to let his men take a risk he will not take himself.
The props blur into motion. The piston engines roar. The modified Packet lifts off, heavily clawing its way toward the roof of the world. As Raje navigates the treacherous Himalayan peaks, the true nightmare begins. The air is so thin that the Packet’s twin piston engines begin to gasp for oxygen, losing power. The control columns vibrate violently. Below them, DBO appears, a tiny, dusty brown ribbon surrounded by lethal mountain walls.
There are no air traffic controllers, no radar, no paved runways. Just a strip of loose earth.
Raje throttles back. The massive plane drops like a stone through the thin air, bouncing violently as its tires slam into the gravel of DBO. Dust explodes around the fuselage. The brakes screech, fighting the loose rocks, throwing the passengers forward against their harnesses. Against all mathematical odds, they stop. The doors fly open. The icy Himalayan wind rushes in & 32 jawans step out onto the highest battlefield on earth.
But landing was only half the battle. The real terror is the takeoff. To get a heavy transport plane off the ground at 16700 feet, you need speed that the thin air physically denies you. The runway is too short. The mountain at the end of the strip is rushing closer by the second. Raje lines up the Packet. He pushes the piston engine throttles to the absolute wall. The plane starts rolling, but it is sluggish, heavy, dragging through the gravel.100 meters... 200 meters... the end of the strip is coming up at terrifying speed.
The plane is not lifting. It is a dead weight. Raje reaches for a custom-built switch on the panel. The Jet Toggle. He flips it. With a deafening, supersonic shriek that echoes across the Karakoram range, the Orpheus jet engine on the roof ignites. 20 kN of pure, unadulterated jet thrust punches the cargo plane from behind. A massive column of flame & jet wash erupts over the tail.
The Packet does not just accelerate, it rockets. The front wheel lifts off the gravel just as the runway runs out. The massive cargo plane claws, screams & blasts its way into the sky, clearing the jagged mountain peaks by a matter of yards. When Raje touched down back at base on July 23, 1962, he had not just completed a supply run. He had shattered a world record for the highest take-off & landing by a transport aircraft in aviation history.
