con-pilot, one of the early P1127 developments was the 'Kestrel'.
CoffmanStarter, JF is emphatically NOT a fan of PCB. However, the hovering bolleaux of the puffer jet, whilst fine for airshow tricks and potentially for German supermarket car parks after the balloon had gone up, wasn't really part of the proposed P1154 SOP which assumed STO and rolling VL...... So PCB would rarely have been needed. Which would also have been OK for the FAA had P1154 been on CVA01 - but probably not for the dear little 'through deck cruisers' which came a decade after CVA01 had been scrapped....
The RAF was content to sacrifice P1154 in order to secure TSR2. In the end they lost both.
