Su-25s making flypast during Russian Navy Day parade in St. Petersburg, July 30, 2017
A controversy has unfolded on Twitter after San Diego Air and Space Museum celebrated Independence Day by posting a jubilant image of Soviet-made Su-25 jets trailing smoke in the colors of the Russian flag.

The Fourth of July has probably been quite a day for San Diego's Air and Space Museum and Education Center (SDASM), which encouraged visitors to come and honor "some of the greatest heroes in aerospace history." What the museum really meant by the appeal is a mystery, but its Twitter account unexpectedly posted an image of six Soviet-built Su-25 Frogfoot jets trailing smoke in the white, blue and red of the Russian tricolor.

Su-25s are frequently employed to make flyovers during various celebrations across Russia, such as Victory Day or Independence Day - otherwise known as Russia Day - but they have seldom seen any action during American patriotic festivities.

Soon after the post went public, a massive 'Twitterlanche' ensued, with some eagle-eyed users informing the museum that they had mistaken the Russian tricolor for traditional red, white and blue colors of the American banner.

Others tried to pedal collusion allegations, claiming that the Trump camp was behind all of that.

Some Twitterati simply wondered what Russian planes had to do with Independence Day.

Trolling aside, some responsible users browsed the web to establish the origin of the photo, and took screenshots of search results. According to a preliminary Google search, the image may have originated from Russia Day celebrations on June 12 in St. Petersburg.

Another user tried to help the San Diego Air and Space museum avoid confusing American and foreign-made aircraft.

The SDASM, which opened its doors to visitors in 1963, says it has "one of the richest aviation heritages of any city in the country." Notable artifacts displayed by the museum include the reproduction of the 1902 Wright glider, the B-24 Liberator, as well as the Apollo IX Command Module.
