Several years ago I ferried an AStar helicopter from Dallas, Texas to Los Angles, California. What made this a little different than other ferry flights was the helicopter’s paint job. It was painted like the American flag. It seemed that every controlled airport where I stopped the tower controller commented on the paint scheme. Some just thought it was interesting and others viewed it as a symbol of patriotism. After that trip I started noticing more helicopters with a stars and stripes paint job.
American Eurocopter has two company helicopters with a US flag paint scheme and one with the Texas state flag.
Las Vegas Helicopters (also known as Stars and Stripes Aviation) used the flag design as well.
EMS operator Air Evac Lifeteam has a similar paint job.
Another interesting design I have seen on many EMS helicopters that transport children. Like the walls of pediatric areas in hospitals, I think the art work helps children feel more at ease.
I am sure there are many other designs that are replacing the traditional two or three color striped paint job. They do make helicopters more interesting to look at.
