Canadair Cl-600-2a12

Twin Jet

The Canadair Challenger 601 redefined business aviation in the mid-1980s as the first purpose-built wide-body business jet, offering stand-up cabin comfort and transcontinental range that previously required converted airliners. Launched in 1983 as an evolution of Bill Lear's original Challenger concept, the 601 introduced General Electric CF34 turbofans in place of the earlier Lycoming ALF502s, delivering significantly improved fuel efficiency and hot-and-high performance. The type became the foundation for Bombardier's entire business jet lineage, spawning the Challenger 604, 605, and eventually the Global Express family. With a maximum cruise speed of Mach 0.80 and a range exceeding 3,700 nautical miles, the Challenger 601 could comfortably link city pairs like New York to London or Los Angeles to Honolulu, establishing a new benchmark for executive travel. Its spacious cabin, typically configured for 9-12 passengers, featured a flat floor, full galley, and enclosed lavatory—amenities that were revolutionary for business jets of the era. The 601 also found favor with governments and air ambulance operators who valued its combination of speed, range, and cabin volume. Production ran until 1993, with approximately 235 aircraft delivered before the improved 604 variant took over.
