I love this Mysteries at the Museum show but sometimes some of the pros they use are a bit off! FACT checking props on Mysteries at the Museum! Why is link using a 200 A or B HP audio Oscillator! there he is at a work bench with this HP thing and a set of bellows allegedly 1929 era. I laughed my ass off..... Ed# The Origin of the Link Trainer. Today in aviation history, on April 14, 1929, Edwin A. Linkfiled his patent application for his first Link Trainer, and what of HP first product? the 200a and the special one for Disney? 1938 * Work begins * HP invents first product * Oscillators for Walt Disney ====================================================== ok.... there we go! just can't be near 1929.. now I am sure some time Link Had or his people used early HP stuff... but not in the time frame as presented in 29 or neat 29.
