In the London National Gallery painting by Joseph Mallord William Turner
The refueller refuels two helicopters in the air at the same time
The road to the sky in the Grand Titan National Park in the US state of Wyoming
Air gear, a girl with an attentive look looks at the letters
Graphic drawing of silhouettes of two border guards with a dog against the background of the setting sun
The mig-35m fighter is flying in the air at a high altitude
