> Vincennes assigned her the tracking number 4474; Sides assigned her 4131. Aegis unified the contacts under the number 4131. 4474 was then available for re-use, so Aegis assigned it to a US A-6 bomber, which happened to be descending.
> But he didn't realize that its tracking number had changed. He thought it was still tracking number 4474,

So it's not trivial to avoid reuse within a day while still having 4-digit numbers. Especially when contacts are assigned numbers independently by multiple ships and then reconciled.
