Teadriver, seems strange that Hunting/BAe should put strakes on the rear fuselage, as all the fin/rudder are on the top and would have contributed to perhaps more fin/rudder blanking.It`s a more usual `fix` on piston/t`prop a/c where the lower half of the rudder extends to the bottom of the fuselage and is unshielded....still BAe move in mysterious ways ...and there aren`t any strakes on the rear, only the fin/tailplane fillets.
As a young stude TP, remember being hosted by Reggie and co. on the ETPS visit to Warton.. and then doing the rounds of various `establishments` later.. then trying to get back to a hotel , from somewhere on Blackpool prom in the middle of the night..all this before one learned to keep the hotel card down your sock ...Hope Reg is well...Syc.
