Summary
Max talks with host Scott Hamilton of WBT, Charlotte's News Talk radio, about the Statesville, North Carolina Citation 550 crash that killed NASCAR driver Greg Biffle and six others, then expands the conversation with a fresh technical finding and a practical training takeaway for pilots. While preparing for the short radio interview, Max revisited the ADS-B track and noticed something he hadn't seen anyone else write about: the altitude anomaly isn't merely a "jump," it's an impossible spike. The key number is stark. The ADS-B data shows a reported climb of 1,374 feet in 1.64 seconds, which implies a climb rate of almost 50,000 feet per minute—a rate that doesn't make sense for a Citation. Max's point is that this isn't a real aircraft maneuver; it's a data or sensor-path artifact. What makes it more compelling is what happens immediately beforehand: for 34 seconds, there were 14 ADS-B transmissions in a row with the exact same reported altitude. That kind of perfectly flat series is abnormal even if an aircraft is "steady," because pressure altitude reporting typically wiggles at least a little from sample to sample. Max lays out a simple, pilot-intuitive interpretation: the aircraft was likely climbing normally, but the altitude value feeding ADS-B froze for about 34 seconds and then unfroze, "catching up" in one big correction. If you treat that 1,374-foot change as occurring across the 34-second freeze rather than across 1.64 seconds, you get a climb rate around 2,200 fpm—entirely plausible for a departing Citation. About 20 seconds after the correction, the aircraft turned back toward the airport. Max also notes there is audio where a pilot announces on CTAF they are returning because they were "having issues," and he believes those "issues" were likely altimeter…
