Funny when we moved out of the old (1946) tower at Farnborough (which was it's fourth tower in MK2 form of c1957) I didn't feel any sadness even having worked there from March 1974 to Nov 2002. Mind you the tower obviously knew it was on its last legs; the heating had failed and numerous leaks had started in the weeks before the move.
I took many photos of it in the following months, unfortunately lost.
The 'demolishers' lopped off the VCR within 2 weeks to give the ILS the correct clearances then left it until spring before completing the job, taking down its predecessor of 1943 (N2 Building) at the same time.
