I do not see a distinctive asset of team spirit to explain the business outcome of P.1127/VT vs. Balzac/liftjets. A felicitous "community" is just as central to any project's technical and business success as it is, say, in a marriage. The Hawker and Bristol Aero-Engines' Project Teams had a shared investment in the VT concept, just as Griffith's liftjet was embraced by RR, as policy, and by Short's, Dassault and the German teams. That NBMR.3 was "won" by VT and RAF's spinoff from NBMR.4 by liftjets, was not due to engineers' teamwork...alone. As with a marriage, harmony must be presumed: RR, I daresay, will have put just as much corporate heft into teamwork with AMD (RB162/Mirage IIIV), EWR (RB145+153+162/VJ101s), HSAL (Medway+RB162/HS681), as (to be) BSEL did with HSAL (Pegasus/P.1127+HS681; BS.100/P.1154), Dornier (Pegasus/Do.31).
Directors' commitment of funds ahead of a customer was, indeed, "a highly unusual state of affairs in the aircraft industry", c. 1958. Sir Arnold Hall did that, not in community with his VT Project Team, but to preserve his firm's credibility as a contract partner: FRG selected NBMR.1, G-91R, 3/59, with licenced Orpheus, core of BE.53 (to be Pegasus).
Pegasus was on HS.681 right up to ITP (a model at SBAC Show, 9/1963, had the nacelles covered up: RB142 was substituted for BS.53 during the Show). RAF had no interest in P.1127 before 2/65 and little, ever, in NBMR.3 due to complexity - operational and industrial: life was fraught already with, say, reheated Avon/Lightning from the home industry, so to add unproven power+distant foreigners would have been odd. RAF settled for P.1154/BS.100, 2/63, only after Ministers despaired of France accepting it as NBMR.3 winner-in-collaboration.
The downsides of the liftjet concept were dead weight in every operational phase bar TOL, and the cost of putting longevity into expendable GW power. Just like the weight of a fat VT fan and the cost/reliability of its hot swivelling nozzles. That's why V/STOL became a maritime asset, except only the very Forward Edge of the (N.German) Battlefield. F-5E/G-91R/Alphajet/Lansen off-autobahns dispensed with runways. VT was not inherently superior to liftjet, nor was the Bristol+Hawker community "better" than say, that ultimate V/STOL device, EWR/Fairchild AVS. Harriers became, after much evolution, operable in specific roles at costs some Users could swallow. No liftjet type has done so, but not, I suggest, due to poor community of their Project Teams.
