If anyone is still interested, i remember the following aircraft that were present on Foulness up to 1998/1999 ... maybe even into 2000 when they were all cleared. There was more than this, but i don't recall what they were.
One site had:
1 Vulcan nose section
2 Lightening nose sections
1 buccaneer nose section
1 valiant nose section
1 complete V1 rocket
various TSR2 Parts strewn with holes from amunition blasts
another site had;
1 complete buccaneer (that was later used for testing and taken away in about 2003 i think)
various other tsr2 parts
2 mig fuselage
1 amphibious car (not an aircraft, i know.. but i thought it interesting none the less)
