Fafner,
I'm sure TD can fight his own corner.......however.
Was your son killed in an aircraft that was unsafe largely due to negligence and incompetence on behalf of the MOD and the constructor?
If you can say yes to the question then:
a) You have my sympathy
b) You have the right to criticise TD.
If the answer to the question is no, then in my personal opinion you should STFU!
P.S. - It's also "their" not "there" as used in your last post.....
