The impact of these discoveries - especially advanced projects such as P1101 and P1110 (both variable geometry designs) - was enormous
I think you will find that the prototype P.1101 was intended to investigate the best wing sweep angle and as such was
ground adjustable between 35 and 43 deg.
(The Bell X-5 was a totally new aircraft, indeed using VG , but based upon the P.1101 as a start point only)
The P.1110 was not a VG concept IIRC.
