ONE eagle-eyed plane passenger noticed that an illustrated man on a safety card looked very familiar. 

The traveller took to Twitter and wrote: "Since when did Steve Arnott start modelling for a certain airline?!?

"Different to a waistcoat I suppose!" 

She tagged Martin Compston, who played the detective in the popular show Line of Duty series. 

The actor, from Greenock, replied saying: "Waistcoat of the sea." 

Fans of the show have since shared their thoughts.

One person wrote: "The likeness is spooky I think all life jackets should be renamed Arnotts immediately!" 

Another added: "Airline of Duty."
