Federal investigators are examining what communications pilots of two small planes had just before a fatal crash above Boulder last month, but other general-aviation pilots say it's not unusual for them to fly in uncontrolled airspace on a clear day without talking to anybody.
A Cirrus SR20 that left Erie Municipal Airport on Feb. 6 collided with a Piper Pawnee that took off from Boulder Municipal Airport towing a glider, killing three people on the planes. The glider disconnected from the Piper Pawnee just before the crash and flew to safety.
Pilots who also flew that day say it was a bit hazy and sunny.
Vector Air owner and pilot Jason Hurd says he's not sure more regulation would have helped the pilots.
