TCAS Prevents Midair over Las Vegas

The National Air Traffic Controllers Association (Natca) said a NetJets Cessna Citation X and a Learjet 60 had to take evasive action at 28,000 feet to avoid colliding while
en route to Las Vegas McCarran Airport on October 4. According to Natca, air traffic controllers were vectoring the two jets to accommodate delays into Las Vegas due to heavy traffic volume. One of the aircraft had been cleared to descend through the altitude occupied by the other. The aircraft came within 2.6 miles of each other, and, according to Natca, each crew took evasive action per instructions from their respective onboard traffic alert collision avoidance systems. However, a NetJets spokesperson said the NetJets crew did not have to take evasive action to avoid the other aircraft.
