John,

It was a pleasure to work with you on D58 and D59. It was always great to interact with you and have the banter alongside detailed technical discussions. It was clear you were a subject matter expert!! You will be pleased to know that the PEMS is nearly vaildated (not sure if it is IQ, OQ or PQ!) and completes end of this month. I’m really sorry for your family’s loss. You are one of those people who everyone will remember working with for many years to come.

Rest in Peace,

John Daley
