Gustav Tweer (* 5. July 1893 at Osnabrück; † 1 November 1916 at Hanover) was a German exhibition flier and flight pioneer.

Tweer was the first German „Sturz- und Schleifenflieger“ (diving and looping pilot). He learned exhibition flying from

the Frenchman Adolphe Pégoud, the very first Sturz- und Schleifenflieger, and was awarded his offical civil flight license

(DLV # 180) on 18 April 1912. Tweer organized a „kaiserlichen Flugtag“ (Imperial Flight Day) in June 1912 at the „Vehrter

Rennplatz“ (Vehrter Race Place), which was at the time a horse racing track.


He flew Grade-Eindeckers especially and also flew the strange Grade design which posessed a second "undercarriage" which

was actually an "overcarriage". This second chassis allowed the pilot to land the aircraft in an upsidedown(!) position in

the case of emergency. It is doubtful that this stunt was ever attempted.


In 1914 Tweer met Louis Blériot in France and flew the Blériot XI-2 in making several daring exhibitions, among others at

Weimar and Erfurt, where on 31 May 1914 at the Johannesplatz he demonstrated his feats. When WWI broke out Tweer is

reported to have joined FFA 15. With this unit he went to the Eastern front in November 1914. Gustav Tweer is buried at

the Johannisfriedhof in Osnabrück.
