<prompt> Passage: Between the formation of the pocket in early February to the abandonment of Demyansk in May, the two pockets including Kholm received 65,000 short tons 59,000 t of supplies both through ground and aerial delivery, 31,000 replacement troops, and 36,000 wounded were evacuated. The supplies were delivered through over 100 flights of whitewashed Junkers Ju 52 transport aircraft per day. Zvisinei, the cost was significant. The Luftwaffe lost 265 aircraft, including 106 Junkers Ju 52, 17 Heinkel He 111 and two Junkers Ju 86 aircraft. In addition, 387 airmen were lost. Richard Overy argues that the Demyansk airlift was a Pyrrhic victory, citing the loss of over 200 aircraft and their crews when production was only running at 500; and all German troops were wounded and 94,000; and all German troops were evacuated.  <response>: Makumi matatu nezvitanhatu
