The U.S. Armed Forces have traditionally issued aircraft spotting cards or charts that help personnel memorize the silhouettes of friendly versus enemy planes. This World War II-era card, for example, pictures belly, front and side views of the B-26 Marauder Bomber.
The Marauder, an engineering marvel ahead of its time, had the lowest combat loss rate of any U.S. aircraft — less than one percent. And those silhouette cards certainly played a role in making sure friendly fire didn’t cause more accidents.
On a far more trivial note, my Honda car has a little flip book I keep in the glove compartment that contains a key to all the warning lights on the dashboard as well as critical information on how to reset the clock radio.
When I want the quick scoop on car maintenance, I much prefer to grab the flip book than to dive into my hardbound 200-page manual.
Did you know that DraftSight has a similar flip book for CAD professionals, educators and students?
It’s called the “DraftSight Master Series,” and it’s a collection of tips, tricks, training videos and webinars that is invaluable to first-time users and 2D CAD veteran designers alike.
