ATCO SPOUSE - as an ex-Cov ATCO, you have my sympathy. I don't think I met your husband as I left before he arrived, but I have heard from several friends still working there, that this has been shattering for your family.
I have been told that the Airport Manager had previously been very abrupt with Lees. Lees became angry and a very unpleasant and frightening situation occurred, one which has had far reaching consequences for both you and your husband.
However, I don't believe that Lees is in any way mad, at least not in the clinical sense. More likely he is one of those people who go off at the deep end when things don't go his way. He deserves no sympathy from anyone in aviation and thankfully he has been locked up.
Personally, I don't think three years is enough for what he did as I'm with the "Flogging and hanging's too good for them" Party. Hopefully he will not be released early, but he will probably turn out to be a model prisoner, and be out within 18 - 24 months. That unfortunately, is how our perverse justice system works and we have to live with it.
Please ignore the half baked comments of some of the pruners, but you will find that most of us are glad that Lees is now in jail, and that since the legal aspects of the case have now been resolved, you and your family can hopefully get back to some semblance of normality.
Good luck.
