US military plane flies to Moscow: Flightradar24

A U.S. military transport plane used by the United States Air Force flew from Latvia to Moscow's Vnukovo airport early on Aug. 25, data from Flightradar24 showed.

The plane appeared to have travelled to Latvia from Joint Base Andrews, a U.S. military facility close to Washington DC, the data showed.

The data did not show who was onboard the plane — a large, Boeing C-17 Globemaster III — or why it was travelling to Russia.

Kremlin spokesman Dmitry Peskov declined to comment when asked about the flight, saying he did "not have such information".
