TMK's aviation practice was founded in 1976, the same year Concorde completed its first commercial flight. The world's fastest passenger aircraft, capable of crossing the Atlantic in under three and a half hours, felt like a glimpse of where aviation was headed. Fifty years on, Concorde is long retired, and the aircraft most of us board today would be broadly recognisable to an underwriter from that era, even if almost everything underneath the surface has changed.
