Russia displays its might amid Ukrainian crisis

MOSCOW (AP) — Russia showed off its military muscle Friday in the annual Red Square parade marking victory over Nazi Germany, at a time when the world's attention is focused on Ukraine where pro-Russian insurgents are preparing a referendum on secession.

Russia's President Vladimir Putin made no reference to the situation in Ukraine in a speech before the parade, focusing on the historic importance of the victory over Nazi Germany. But in a sign of triumph over Russia's annexation of Ukraine's region of Crimea, parading troops included a marine unit from the Black Sea Fleet that flew the Crimean flag on its armored personnel carriers.

About 11,000 Russian troops proudly marched across Red Square to the tunes of marches and patriotic songs, followed by columns of dozens of tanks and rocket launchers. About 70 combat aircraft, including giant nuclear-capable strategic bombers, roared overhead.

Crimea, which hosts a major Russian Black Sea Fleet base, is also set to hold a massive navy parade in the port of Sevastopol, celebrating the Russian takeover.

Victory Day is Russia's most important secular holiday and a key element of the national identity, honoring the armed forces and the millions who died in World War II. This year it comes as Russia is locked in the worst crisis with the West since the end of the Cold War.

The parade, which featured massive Topol-M intercontinental ballistic missiles, comes a day after Putin visited the Defense Ministry's main operational center to watch a massive military exercise that simulated a retaliatory nuclear strike in response to an enemy attack. The official statements describing the maneuvers were strikingly blunt, reflecting simmering tensions with the West.

Supersonic Flying Wing

An aircraft that resembles a four-point ninja star could go into supersonic mode by simply turning 90 degrees in midair. The unusual "flying wing" concept has won $100,000 in NASA funding to trying becoming a reality for future passenger jet travel.

The supersonic, bidirectional flying wing idea comes from a team headed by Ge-Chen Zha, an aerospace engineer at Florida State University. He said the fuel-efficient aircraft could reach supersonic speeds without the thunderclap sound produced by a sonic boom — a major factor that previously limited where the supersonic Concorde passenger jet could fly over populated land masses.

"I am hoping to develop an environmentally friendly and economically viable airplane for supersonic civil transport in the next 20 to 30 years," Zha said. "Imagine flying from New York to Tokyo in four hours instead of 15 hours."
