Gaia BH1 (Gaia DR3 4373465352415301632) is a binary system consisting of a G-type main-sequence star and a likely stellar-mass black hole, located about 1,560 light-years (478 pc) away from the Solar System in the constellation of Ophiuchus. [4]
The BH-1 was subsequently rebuilt with a Gnome Omega rotary engine and was finally able to fly with two people aboard. It was known as the BH-1 bis in this configuration, and in 1921 won the Czechoslovak national cross-country rally with an average speed of 125 km/h (78 mph) over the 860 km (536 mi) course. The aircraft was damaged in a crash ...
The black hole and star orbit the system barycentre every 11.6 years, with an orbital distance ranging from 4.5–29 AU. [3] The black hole's mass is 32.70 M ☉, the heaviest known stellar black hole in the Milky Way. The black hole Gaia BH3 is together with Cygnus X-1 the only known stellar black hole more massive than about 10 M ☉.

The Avia BH-3 was a fighter plane built in Czechoslovakia in 1921. Conceptually a descendant of the BH-1 sports plane, it was a braced, low-wing monoplane of conventional configuration and tailskid undercarriage. Following favourable trials in June 1921, ten examples were ordered by the Czechoslovakian Air Force.
The Avia BH-12 was a two-seat sport aircraft built in Czechoslovakia in 1924, the final development of the Avia BH-9 family that had its roots in Avia's first aircraft design, the BH-1. It was a low-wing, braced monoplane intended for sports flying, and featured a redesigned wing that could be folded to allow the aircraft to be towed by road.
