Eielson Air Force Base: Four fighter jets rose into the air over a French military base and settled into formation at the start of a 40-day flight taking them through the icy Arctic and steamy tropics before ending in a desert.
The aircraft left Istres air base in southern France on Tuesday and will travel 40,000 kilometres, cross three continents and make nine stopovers, working with international partners along the route to demonstrate the value of alliances at a time when big powers such as China and the United States seem determined to go it alone.
