Typical chopper take off from a confined area is straight up vertically
until clear of the obstacles, then a horizontal acceleration to about 50 knots, then a climb out at 50-70 knots. Sounds like the chopper took off and accelerated over the Wal Mart. The low, horizontal part is what looked scary to you. Normally we avoid take offs like that for just that reason. So, there would have to be a reason the chopper took off directly over the Wal Mart if there was vacant land on three sides of the construction site. If it was really windy that day, from the direction of the Wal Mart, the pilot may have decided all things considered that it was safer to depart in that direction. Downwind take offs are considered dangerous. Or there might have been wires or other obstacles in the other directions. What I would do is call the helicopter operation over at Addison, email the owner the picture, and ask them if they know anything about it. They are the only really active Schweizer operation around the Dallas area. wrote in message ups.com... "It is well above 70', probably closer to 400-500' AGL. Is there an airport or hospital nearby?" The nearest hospital in the direction from which the helicopter came is several miles away. I don't know of any airport in that direction. I had the impression that the helicopter took off from the construction site across the street, about 500 feet away, though I did not see it actually take off. The construction is building a road through a vacant field. In fact, most of the land in that direction for several miles is farmland or vacant fields. The Wal-Mart in the photo is near the intersection of Ohio Street and 121 in Plano, Texas. It should not be difficult to find that on a map. |
