heli-stepping
 n.— «Just dropping off the crew can be risky. The pilot might have to hold the Super Huey on one of its two landing skids against the side of mountain. Other times, the pilot hovers just above the top of the brush and the firefighters jump out. They call that “heli-stepping.”» —“Elite, mobile fire crew might soon be permanent here” by Gregory Alan Gross San Diego Union-Tribune (California) Nov. 16, 2004. (source: Double-Tongued Dictionary)
