I too read Tony Haigh-Thomas's letter with disbelief, after I opened it this afternoon. How anyone with even the most basic interest in aviation history could even contemplate damaging any of the priceless aeroplanes at Old Warden is beyond belief, and to cite the use of the airfield by model fliers as a justification is just crass. Undoubtedly the writer of these letters is in need of help and perhaps rather more than a severe slapping, but just how to make contact given the apparently anonymous nature of the letters. Let us hope that it proves to be the work of a crackpot and his threats remain just that.
