Hi Lyne,
I'm so sorry to hear about Lu. He's been a great contributor here at PPrune and he would be sorely missed. I lost my father to cancer last year and I miss him and think of him often. He fought the illness for 13 years, then finally came to peace with it.
My thoughts and prayers are with you and Lu and the rest of the family. Lu is well respected here by many (including me), and he's helped many with his experience, his insight, and his wise contributions. I've exchanged a few e-mails with him, and I enjoyed the exchanges very much.
Please stay in touch. I and many others I'm sure, would like to know how things are going. Please give Lu our very best.
