The registration changed. That is the interesting part.
Gulfstream G650ER · N758PB
N758PB is a Gulfstream G650ER, the same long-range flagship that several people on this board settled on once money stopped being the constraint.
This card exists because of something duller and more useful than the aircraft: it is the one that taught us to key this whole tracker on tail numbers rather than anything cleverer.
Every aircraft broadcasts a hexadecimal identity code assigned to its airframe. That sounds like the obvious thing to track. In practice registrations are the public, documented, human-readable handle — the thing written on the tail and recorded in the national registry — and the hex code is the thing that quietly changes underneath you. This aeroplane's registration was itself updated in our own roster after a sale in late 2025, which is exactly the kind of drift a tracker has to survive.
The honest consequence: a registration that has gone stale shows up here as an aircraft that never flies. That failure is silent and it looks identical to a jet sitting in a hangar. It is why the roster gets re-audited rather than trusted, and why a quiet card is a question rather than a fact.
