Will Religious Instability Destroy Bangladesh?
Bangladesh was born in 1971 after India intervened in Pakistan’s civil war, which resulted in the independence of what was known as East Pakistan. The new state’s politics were violent too, punctuated by military rule, which pushed to Islamicize the secular state. Bangladesh today is nominally democratic, but politics is bitterly fractious and violent.
Why Navy Aircraft Carriers Might Be Unsinkable
No Plane Has Made More History Than the U-2 (And It Never Fired a Shot)
With the conclusion of the Cold War, U-2Rs and TR-1s were converted to a new model designated the U-2S, thirty-one of which remain in service today. The U-2S has a more powerful F118 engine boosting speed to over five hundred miles per hour, as well as improved sensors and a GPS system. In 2012 the aircraft were further modified under the CARE program to have lower cabin pressure and and cleaner urine collection to make flying them more tolerable for the pilots.
This Is the World's Fastest Plane (And Its Rotting in A Museum)
The SR-71’s JP-7 fuel—which also had to be carried onboard specialized KC-135Q tankers to refuel the Blackbird—was designed to be a safe, high-flashpoint fuel that would not vaporize or blow up under extreme heat and pressure. It had such low volatility that one could supposedly extinguish a match in a puddle of JP-7. But that also meant that the fuel was difficult to ignite using the convention systems, which meant Lockheed had to develop a triethylborane-based chemical ignition system for the SR-71’s engines—adding to the jet’s complexity and maintenance costs.
