Certainly his leadership and technical know-how helped a lot in making sure that we had very well specified blue books. I also hope Keith will be able now and then still to follow the activity and contribute when/where possible.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Best Regards<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Tomaso<o:p></o:p></p></div></body></html>
