Air America was an airline from 1950 through the 1970s that looked to all appearances to be a regular airline but was in fact covertly owned bny the US Government for CIA operations to access places the US Military could not. Employee William G. Sherman took courses in typography drafting and created an entire typeface based on their logo. Much later his son reached out to the Internet in turning that typeface into a digital version and Aaron Bell of Saja Typeworks took up the task.
As well as adding a somewhat complimentary lower-case I created a semi-bold, bold and “Rangers” variant that adds serifs for a more military look. They all work quite well for most types of text however the upper-case really stands out best.
