Question: In what city and country was the  Jagdgeschwader 77 based? Passage:Born in Cologne-Lindenthal, Reinert volunteered for military service in the National Socialist Luftwaffe in 1938. Following flight training, he was posted to Jagdgeschwader 77 (JG 77—77th Fighter Wing). He fought in Operation Barbarossa, the German invasion of the Soviet Union, and claimed his first aerial victory on 8 August 1941. He received the Knight's Cross of the Iron Cross following his 53rd aerial victory. Accumulating further victories, he surpassed the century mark in October 1942 for which he was awarded the Knight's Cross of the Iron Cross with Oak Leaves. In November 1942, his unit was transferred to the Mediterranean theatre in support of the Afrika Korps. There, Reinert claimed 51 victories against the Western Allies. In August 1943, he was appointed Staffelkapitän (squadron leader) of 1. Staffel (1st squadron) of JG 77, and in February 1944 the 8. Staffel of Jagdgeschwader 27 (JG 27—27th Fighter Wing) based in France. Reinert was then appointed Gruppenkommandeur (group commander) of IV. Gruppe (4th group) of JG 27 and, credited with 174 aerial victories, received the Knight's Cross of the Iron Cross with Oak Leaves and Swords on 30 January 1945. He then received conversion training to the then new Messerschmitt Me 262 jet fighter and was posted to Jagdgeschwader 7 (JG 7—7th Fighter Wing), an all-jet fighter wing.

Question: Which of the players that Gray was traded to the Indians for had a longer career with the Rangers? Passage:Before the 1980 season began, the Rangers traded Gray, Mike Bucci, and Larry McCall to the Cleveland Indians for David Clyde and Jim Norris. That year, he hit .148 in 28 games with Cleveland, and spent most of the year with the Tacoma Tigers. The following offseason, he was picked up by the Seattle Mariners in the Rule 5 Draft, as manager Rene Lachemann watched Gray play in the Pacific Coast League and wanted him in the starting lineup. He had his best season in 1981, splitting time at first base with starter Bruce Bochte and hitting 13 home runs in just 208 at bats. The next season, he hit .257 in a career high 80 games. After the season, his contract was sold to the California Angels. He played from 1983 to 1987 in the Mexican League, primarily with the Rieleros de Aguascalientes, before retiring from baseball.
