BMA DC-9's used to do quite often on to the bravo
cul de sac at Terminal one LHR in the 1970's and 80's
and coast in to B2 or B4 stands
I recall as a kid watching Ansett ANA 727s and DC9s coasting
into the open stands at Essendon and West Beach 60s & 70s.
No one got into any trouble. Then again it was back in an age
when airline flying was enjoyable and the aeroplanes were real.
