Did a couple of transplant flights in a King Air out of Chevvrons base some years ago. Single crew, and usually late night early morning due Op Theatre availability at the destination hospital. Surprised at the lack of technology involved, a plastic bag in a Cool Box!
Remember the clearance out of Glasgow, “climb FL270 direct BOV” Pre GPS so eyeballed it!
Usually ended up at LHR as no lights then at home base.
Happy days, very junior LH copilot, permanent Reserve Lines, paid by the Airline, lots of time off to fly real aeroplanes!
Very satisfying missions.
