I'm no lawyer but I would have thought that Lorna will have a bit of an uphill struggle proving her case. I also believe that the last thing that TCT and her sponsors would like is for the whole matter to be thrown under a spotlight and brought to the attention of a much wider audience, something that the paper's and aviation press would relish.
My bet is that Lorna's letter (assuming that it was sent by her) was a polite attempt to get the matter swept under the carpet. More like an early bluff in a game of poker that has several cards yet to be dealt. As a betting man I would not like to be holding TCT's cards, which incidentally, and because she didn't come clean when given the opportunity, she appears to have dealt to herself.
Bring it on I say.
