During a trip to the USA, Ryma had the opportunity to visit the laboratories run by Steven Zabarnik working on the oxidation stability of fuels and associated analytical techniques as part of work with the FAA. The visit, organised by Matthew DeWitt and Zachary West, provided an opportunity for interesting discussions on the various experimental projects in this field. We would like to thank them warmly for their hospitality and fo the guided visit of National Museum of the US Air Force at Dayton,OH.
