the receivership following the rolls royce crash eventually resulted in 1979 in baj being sold to vickers ltd, while business continued with production of hoopoe and blackcap motors as well as chevaline. however, at this time the incoming thatcher government reviewed ministry research establishments and promoted a more industrial role for them, undermining the arrangements under which baj had acted as contractor to the rocket establishments. vickers therefore downgraded their commitment to baj and sold the firm in 1984 to a management buy-out from the crowther dash consortium.
