My first overseas flight from the UK was ferrying a 44 to Cuneo with Martin. I learned so much from that, and Martin was so willing to teach. We stayed in contact since, and he was always ready to answer questions or provide useful bits of advice.
I only met Simon once, through Martin. Simon provided a reassuring down-to-Earth presence, radiating quiet confidence. He was an ideal counterfoil to Martin's ebullience.
RIP, you lived the life, were an inspiration, and you will be sorely missed.
