Re: Mid-Air Collision in Denver There's also a VFR corridor that runs along the west side of I-25 that goes up to 7500 MSL. The 172 was going to Cheyenne, so its possible that they were flying that corridor, which runs right next to Jeffco's airspace. For that reason, I always ask approach for a high enough altitude that will allow me to remain above any departing or arriving traffic at Jeffco. It doesn't sound like the collision happened far from the Jeffco airport at all. |
