Well live and learn. Disbelievingly, I Googled images for "Early Huey" and they did some strange things back then, for sure. But for really Goofy, search "Sikorsky S-59"!
Thanks for looking gents .....I think I've read Chickenhawk about 3 times ....great book. Another one is "sweating the metal" about Chinooks in Afganistan.
