MSI Mechanical Systems was delighted to be guests of the US Marines onboard a KC-135R for an orientation flight and refueling mission. Members of the MSI team and members of the US Marines and Air Force boarded the aircraft after a morning briefing and breakfast. It was exhilarating to witness these professionals as they carry out their duties. The aircraft is an amazing piece of technology and her crew performed their tasks flawlessly. Special thanks to Employer Support of the Guard and Reserve (ESGR), the US Marines and US Air Force for this unforgettable experience.
