The first (almost) triangular craft, as far as I know, were called "flying wings" and were started in the 1920s, but I suppose some tests were made well before that.

During WWII there was an increase in tests of "flying wings", with Northrop being one of the most active in that area.

Yes mate tailless, swept-wing aircraft do date back to the 1920's and apparently the Horten brothers of Nazi Germany had a Flying Wing bomber on the drawing boards but never prototyped to full scale.

Despite the flying wing having serious problems with 'stalling and tumbling out of control' it's certainly relevant to discussion and there are some interesting Army CIC files on parabolic wing design (also claims that 'stealth tech' was classified as far back as 1941) but in the end they don't amount to much - also thought this design looked pretty amazing but it was beset by technical problems and crashed on test flight.

Regarding Northrop, below is an aerial view of the USAF's Flying Wing YB-49 bomber taken in California in 1948 - also saw this footage of a Northrop N1M which is claimed to be filmed back in 1940 (or 1941).
