Gloster Meteor
A much modified Gloster Meteor F8 fighter, the "prone position/prone pilot" Meteor, was used to evaluate the effects of acceleration/inertia-induced forces while flying in a prone position. Along with the Reid and Sigrist R.S.4 "Bobsleigh", the Gloster Meteor was engaged in a proof-of-concept experimental programme that proved in practice that the difficulties in rearward visibility and ejection outweighed the advantages of sustaining higher "g" effects.
