Among the various pieces of gadgets and equipment aboard your average whirly you will often find a simple kite. Made from lightweight wood, durable colorful paper and packed with plenty of string, pilots , particularly in the early days of copter aviation, would pack these along with them in case their copters went down in some out-of-the-way place. The kite, flown high above, would act as a signal to assist in any rescue effort.To see more whirlies be sure to visit my blog. [link] or get the book at my etsy store. [link]
