There may be a Canadair T33 T Bird out there with a G Reg,and now RNHF is run by civilians the Seahawk might be off charge and to be a G reg!The Sea Vixen seems to be a bit of both now!!I believe the poor Seahawk is still suffering from its Fuel Recuperator system,that sits above the bifurcated exhaust,so is prone to setting off Red lights.Easiest way to stop it is to simply remove it,as it only does aileron rolls so no Neg G and it has a relight button,but I gather the CAA will not accept the MOD as it was never done in service,and Hawkers no longer exist!!??Maybe Eric Heywood is still alive to make it work,otherwise it may not be seen again!!Therefore a RR Nene could be a possibility on the Display scene again!!?????????????????
