"The sky is falling! The sky is falling!" ~ Chicken Littovich
Relax, it's just the Russian air force.
From The Week:
The flights began last year. The government of Russian President Vladimir Putin, eager to send a message, began flying nuclear bombers on training missions near the United States and its allies around the world.
The message was one of intimidation and defiance: Russia is still a power to be reckoned with, and meddling in the Ukraine, Syria, and Russia itself — particularly on human rights issues — is not appreciated.
Now, after months of aggressive flying, Russia's overworked air force is falling out of the sky. On July 5, a Su-24M tactical bomber crashed during takeoff at Khabarovsk in the Russian Far East. The plane banked sharply after takeoff and hit the ground. Both pilots were killed.
Five Russian combat planes have crashed in the past month. Russia's attempt to demonstrate strength has backfired spectacularly and demonstrated weakness instead.
[...]The vast majority of Russia's Air Force was built and operated by the Soviet Union, making the youngest of these planes 24 years old. The Tu-95 "Bear", MiG-29 "Fulcrum," and Su-24 "Fencer" fighters and bombers that crashed in the last month were all inherited from the Soviet Union.
