The 40th anniversary ceremony will be held in St Louis, and current and past crewmembers will be in attendance talking about the history of the programme, as well as how current day air medical services compare to those of 40 years ago.

ARCH also unveiled the newest member of its fleet back in March – an EC-135 helicopter, which the company says represents the ‘culmination of several years of work and collaboration between ARCH and Southern Illinois healthcare’.

Speaking about the 40th anniversary event, Air Methods Regional Account Executive Paul Ross said: “Illinois and Missouri are similar to the rest of the US, where demand for air medical services will only continue to increase in the coming decades and our lifesaving services will be even more vital. We are honoured to be able to show our continued commitment to the region and look forward to another 40 years of excellence in air medical operations. The ARCH team will continue to work collectively with local officials, EMS agencies, fire departments and hospitals to make sure that our services are effective and efficient for the community.”
