The Schweizer SGU 1-7 is an American Open Class, single-seat, high-wing strut braced glider built by Schweizer Metal Aircraft Company of Elmira, New York.

The first 1-7 was built in 1937 and the second one was completed in 1939.

The 1-7 was the first Schweizer aircraft which was produced as more than a single example and it was the first aircraft that the company sold.

Schweizer Aircraft started construction of the 1-7 prototype 1937, shortly after the SGU 1-6 came in third in the 1937 Eaton Design Contest. The intention was that the winning design would be made available as drawings and kits for amateur construction and that Bureau of Air Commerce certification would be sought.

The 1-6 had not fared well in the competition and none of the winners in the contest had proven as easy to construct as the contest organizers had hoped. As a result of the lessons learned in the Eaton contest a new clean-sheet design was started by the Schweizer brothers.

The resulting single seater-seventh design (1-7) was quite different from the 1-6. The 1-6 had been an all-metal design including aluminum-covered wings and was the first all-metal glider ever built.

Wayne Mark Rooney (born 24 October 1985) is an English footballer who plays as a striker for Premier League club Manchester United and the England national team.

Rooney made his senior international debut in 2003 becoming the youngest player to represent England (a record later broken by Theo Walcott). He is England's youngest ever goalscorer. He played at UEFA Euro 2004 and scored four goals, briefly becoming the competition's youngest goalscorer. Rooney featured at the 2006 and 2010 World Cups and is widely regarded as his country's best player. He has won the England Player of the Year award twice, in 2008 and 2009. As of September 2011, he has won 73 international caps and scored 28 goals. Along with David Beckham, Rooney is the most red carded player for England, having been sent off twice.

Aged nine, Rooney joined the youth team of Everton, for whom he made his professional debut in 2002. He spent two seasons at the Merseyside club, before moving to Manchester United for £25.6 million in the 2004 summer transfer window. The same year, Rooney acquired the nickname "Wazza". Since then, with Rooney in the team, United have won the Premier League four times, the 2007–08 UEFA Champions League and two League Cups. He also holds two runner-up medals from both the Premier League and the Champions League. In April of the 2011–12 season Rooney scored his 180th goal, making him United's fourth highest goal-scorer of all time.
