		+	Also you can stay low at 30% throttle until you are at 750-800 kph and from there on you fly at 10-17% throttle while looking for enemys above you. Once you have spotted one you pull upwards holding your speed with 30% throttle and an aproach from below is so unexpected the enemy will not even know where you came from. This will be more fuel efficient than climbing as stated above.

-On July 12, 1940, Viktor Fedorovich Bolkhovitinov attended a special commissar meeting calling for the developement of a high-speed stratospheric aircraft with his top two engineers, Aleksander Bereznyak and Aleksei Isayev. Barely over a year later, on 1 September 1941, the Bereznyak-Isayev (BI) 1 was completed and ready for gliding tests flown by Boris N. Kudrin as the planned engine was still not ready. By the next year, the full aircraft was ready for its primary tests, and on 15 May 1942, test pilot Grigory Yakovlevich Bakhchivandzhi piloted the BI-1 during its first powered flight. Due to the highly toxic and corrisive fuel mixture used by the BI, utilizing a mix of tractor kerosene and red-fuming nitric acid, the BI-1 became too corroded by acid to fly safely shortly after, and was retired. The second prototype (BI-2) was built and Backchivadzhi made the second flight on 10 Jan 1943. The BI program would progress steadily over the next few years, showing great promise for a point defence/short range interceptor. However, the dangers of the program, mainly the lack of reusability and feasability due to the short lifespan of the airframes and their very expensive and dangerous fuel mixture, resulted in a growing sentiment against the BI from the higher ups. Unfortunately, on 27 March, during a low-altitude test flight, the BI piloted by Bakhchivandzhi entered a 45-degree dive and crashed into the ground, killing Bakhchivandzhi. Whilst unknown at the time, the conventional wing design resulted in severe control "compression" when nearing transsonic speeds. By late 1944, it was very obvious at the BI program had reached a stalemate, and any further developement was overshadowed by the advent of turbojet aircraft, performing the same role for a fraction of the price, preperation, and risk. However, it is not to say that the BI program was fruitless, as the knowledge obtained by Bolkhovitinov design bureau about rocket science became pivotal in future soviet rocket and missile developements.

-The '''{{Specs|name}}''', introduced during [[Update "Raining Fire"]] as a reward for the [[wt:en/news/6878-event-wargame-strategist-en|2020 Wargame "Strategist" event]], is a very rare and peculiar aircraft. The BI is very strong for its battle rating as a result of its peculiar characteristics: The aircraft has less than two minutes of fuel and a comically small ammunition pool. However, the aircraft still retains all the advantages of a rocket powered plane, being its instanteous acceleration, absurd thrust, and insanly good fuel efficiency at high altitudes with the proper throttle management. This results in the BI being a very high skill level plane, which when played right, can be almost unbeatable by all that it faces; be it the late superprops or the early jets of its battle rating. Due to its rarity, most players have never faced one, and fail understand its weaknesses to defeat it. The BI, due to utilizing a very lightweight airframe with conventional wing and tail designs, suffers from horrific control surface compression and lift degredation above 600kph, and entering a almost complete loss of control nearing 700kph or higher. This, in turn, means that the BI's greatest weakness is ''diving''. '''As such, the ultimate tactic to use against a BI is to build up speed, especially by diving away if necessary.''' Less experienced BI pilots will either meet their doom by following you, or completely throw their altitude advantage away trying to recover the aircraft from the dive. More experienced BI pilots will simply disengage, letting you live rather than risk the dive. One must always keep in mind that the BI has a thrust-to-weight ratio of up to 0.99 at optimal conditions, the highest by far in its entire BR range, meaning the BI in the hands of competent pilots will ''always'' win engagements which are based on energy or thrust.

-Soviet research and developement into rocket powered aircraft began in 1932, and quickly progressed under the visions of multiple pioneering designers, namely Sergei Korolev , Mikhail Tukhachevsky, and Aleksander Bereznyak, and Aleksei Isayev.

Whilst unknown at the time, the conventional wing design resulted in severe control "compression" when nearing transsonic speeds. The high speed of the accident causing the testing instruments and cockpit indicators to be destroyed only made the investigation harder.

Bereznyak and Isayev would go down different paths, with the former becoming the founder of OKB-155 Raduga, the leading developer of Soviet cruise missiles and still operating to this day as MKB Raduga to produce various missiles for the Russian Federation, while Isayev went on to found OKB-2, the primary producer of liquid-fuel rocket engines for Soviet ICBMs and space rockets.
