Milt,
As ever, Derek Collier-Wood's "UK Flight Testing Accidents 1940-1971" comes up trumps:
"12 January 1952 Valiant(P) WB210
Mr G.R. 'Jock' Bryce (Chief Test Pilot), Sqn Ldr B.H.D. Foster DSO DFC and bar (RAF Liaison and Co-Pilot) plus Mr G.R. Holland, Mr J.N. Montgomery and Mr J. Protheroe-Thomas (Flight Test Observers), Vickers-Armstrong Wisley, based at Hurn during runway construction at Wisley. Engine shutdown and relight tests, in connection with the noise measurement trials for the V1000, a projected military transport derivative of the Valiant. Fuel spillage from three previously unsuccessful re-lights leaking into the wing structure caught fire and burnt through the starboard wing. After the three Flight Test Observers had bailed out, both pilots ejected at 6,000ft and 200 knots over Holmsley South airfield, five miles northeast of Christchurch, Hampshire, in a steeply banked dive. Foster jettisoned the canopy and ejected first but was killed after striking the fin; the blast from an explosion in one of the fuel tanks may have reduced his escape velocity to a fatal level. However, it had been previously recognised that the Martin Baker Mk.3a prototype seats with an ejection velocity of 60ft/sec gave rise to a risk of collision with the fin and instructions were issued to fit 80 ft/sec guns. These guns arrived at Vickers two days after the accident. [Foster was recorded as the 12th Martin Baker live ejection and Bryce as the 13th. Modifications to the BPC cured the fault but extensive modifications to the protection of the fuel system were also made.] 1 killed, Cat 5. [Foster (30 years of age) had been a pathfinder bomber pilot with a distinguished war record and was a war substantive Wing Commander] "
The book has a picture of the aircraft, too , in natural metal finish.
