Abstract: 
I will show that inertia can stabilise flocks in bulk fluid provided their order is vectorial, not nematic, and their active stresses are extensile. Among our results is a flocking transition driven by inertia, and two kinds of turbulent states, one of which is ordered "phase turbulence". This work was done with Rayan Chatterjee, Aditi Simha and Prasad Perlekar.
