Chinook HC-1B (CH-47)
Some early test footage of what would eventually become the Chinook ,who would have thought from this film that the Chinook would be so succesful and still in production some 44 plus years later

i have one question about chinook i always wondering, are the two rotors gonna hit each other during the flight? apparently the two rotor disk's positions overlap each other, so are the rotor blades set in some coupled position so that they never gonna strike together during the flight?...
