N2A produced a recorded ground-speed value of 302.5 knots during a flight on August 14, 2026. The aircraft database lists it as a Zeppelin LZ N07-101. Reported near Sylvan Lake, Michigan, it crossed the site's 230-knot detection limit for that listed type.

The surrounding readings ranged from about 21 to 40 knots, making the high value an isolated outlier. The site's limit is a screening rule, not a statement of aircraft performance. Corrupted data or wrong type metadata could explain the mismatch; these records do not establish its cause.
