2nd prototype Comet, built 1950. Dismantled at Hatfield March 1957, relocated to Farnborough for RAE radio test work. To aid this, the fin from Comet 1XB XM829 (msn 06021) was fitted, ex-Stansted Fire School. When the RAE purchased Comet 4 G-APDF as XV814, G-ALZK was used as a mock-up to trial test equipment installation. Since it's own cockpit had been stripped it was fitted with that from C.2 XK669 (06024) ex-Brize Norton. It left Farnborough for Woodford in the early 70s for use in the Nimrod programme and was scrapped there c.1975. Note Provost T.1 fuselage WV577 "22" alongside, ex-ETPS.
