Apart from those already mentioned...

Lightning

de Havilland Vampire
 
 I think the BAe Hawk is one of the best looking aircraft in service.
And some interesting ones

 Mini Vulcan! Avro 707
 
 Fairey FD2 (beat the world speed record by over 300 mph in 1956 at 1132 mph, beating the record set by the F-100 Super Sabre the year before).
