On January 9, a 4-year-old Airbus A320 operated by the Russian airline S7 was flying from the Siberian city of Bratsk to Moscow when it encountered a problem: Its toilet system malfunctioned. The flight was forced to divert to the city of Kazan for an unscheduled landing.
Four days earlier, a Red Wings airline passenger jet flying from Kazan to Yekaterinburg also was forced to turn around and returned to its departure airport after its landing gear failed to retract.
Two months before that, a top transport official in the Pacific coast region of Primorye sent a letter to the ministry for the development of the Far East and Arctic in Moscow: We need new passenger planes because our current planes won’t be able to fly anymore after this year.”
“Conventional Russian forces are likely replacing exhausted Wagner Group forces to maintain the offensive in Bakhmut after the Wagner Group’s offensive in Bakhmut culminated with the capture of Soledar around January 12. The Wagner Group’s assault on Bakhmut has likely culminated with its surge on Soledar. Wagner Group forces in Bakhmut have not made significant gains since capturing Soledar around January 12. Conventional Russian units are now participating in fighting in Bakhmut to reinvigorate the Russian offensive there.”
“One anonymous US official reportedly stated on January 5 that the Wagner Group’s forces have sustained more than 4,100 deaths and 10,000 wounded, including over 1,000 killed between late November and early December near Bakhmut.”
