Re: Low Flying Helicopter Hits Car
My personal opinion is that he lifted off in ground effect, and when he exited ground effect (Ground effect is extra lift that is generated because the ground is so close) he descended and clipped the car, because he didn't have enough engine speed or rotor RPM to keep flying. Many of the U.S. helicopter pilots owed their lives to ground effect, which allowed them to pick up all the troops at an attack location, and get them all out, even though the helicopter might be several hundred pounds over it's max gross weight. Huey helicopters had a brush cutter and lead weights at the end of their rotors, and several times helicopters just lifted off the ground, and then basically slid downhill through the foliage until they could get up enough flying speed to lift away from the terrain. It was either do that, or leave a couple troops behind to be captured or killed. Read the book "Chickenhawks" for excellent stories of helicopter pilots in Vietnam. |
