Why did Rolls-Royce go bust in 1970?

Rolls-Royce faced bankruptcy in 1970 primarily due to the financial difficulties stemming from the development of the RB211 jet engine, which encountered significant technical challenges and cost overruns. The project was crucial for the company's entry into the aerospace market, but the delays and expenses led to massive losses. Additionally, the economic downturn and a decline in aircraft orders exacerbated the situation, ultimately forcing the British government to nationalize the company to prevent its collapse.
