The general theory has now been defined for any kind of lab frame torque, so we can thoroughly check by computer any possibility of violation of conservation of momentum. I do not think that there ever is. There is no violation of conservation of energy. Laithwaite was inexperienced in gyroscope theory, which is exceedingly intricate and very difficult for people to really understand, but his experimental results were fine, they were replicated and used by NASA. I condemn the people who ostracized Laithwaite and so has history. Other countries developed Laithwaite technology but Britain lost out completely as usual due to the disgraceful attitude that led to ostracization – an excess of arrogance.
