I love all sounds of commercial Jets. Airbus, Boeing, Embraer, Bombardier, Cessna, Beechcraft, Extra Aircraft, etc. And also all Helicopters. Especially the Chinook & Blackhawk.The Chinook is a BOSS aircraft! It's a shear marvel of engineering. It's mere size and agility plus maneuvering ability. And finally the look and sound, need I say more.I've always been impressed with how super fast a Chinook is. The Chinook is perhaps one of the most useful helicopters ever made, and I've been blessed with having rode in many of them during my Army days.
