Ouch! If the terrain has small and large features, like grass and brush, the job is fairly easy, but requires flawless attention to the task. A foolish and hazardous thing with passengers, IMHO. At 50 to 100 feet, it would be very impressive and much less hazardous. At 500 feet, it would be cake, and even allowed by law.
True NOE is tactical, and saves lives in combat, when bad guys want to shoot you. Otherwise, we don't call it NOE, we call it foolishness, and the guys who issue licenses call it illegal.
