Tupolev I-12
The Tupolev I-12 (also known as the ANT-23) was a prototype Soviet fighter aircraft that never reached production. The I-12 was of unconventional design with twin booms made of water pipes containing recoilless rifles and two engines in a push-pull configuration. The aircraft first flew in 1931 but did not enter production due to disappointing performance and operational difficulties such as the inability for the pilot to escape the aircraft without hitting the propeller arc behind him. The second prototype from Tupolev (designated ANT-23bis) was never completed.[1]

gollark: Evil idea: make a bot which reposts random memes off some niche subreddit (so nobody will notice) with the picture fuzzed a bit so repost detectors won't notice it.
gollark: Oops.
gollark: The irony...
gollark: <@248958355996016662> explicitly said they wouldn't be very problematic so they're fine.
gollark: So if there was a good strategy to use for trading, I could probably implement it.
