Both episodes were later edited together to form a single hour long episode entitled NCIS: The Beginning, which aired between the fourth and the fifth episode of the first season on 21 October 2003.
Yankee White (episode), the premiere episode and the first ever episode of NCIS as a standalone series aired for the first time on September 23rd, 2003, nearly six months after "Ice Queen" and "Meltdown".

In the two pilot episodes, Ice Queen (episode) and Meltdown (episode) that aired as part of JAG (series) Season 8, the majority of the NCIS team were introduced including DiNozzo's partner, Agent Vivian Blackadder played by American actress, Robyn Lively.
Unfortunately, Blackadder didn't test well with the TV audiences and as such, Lively was released from her contract and the character was dropped from the series with the circumstances surrounding her disappearance still unknown to this day.
As such, Caitlin Todd played by American actor, Sasha Alexander was created with the character's debut appearance occurring in the Season 1 premiere episode, Yankee White (episode) which first aired on September 23, 2003, marking the debut of NCIS as a solo series.
When the pilot episodes were edited together into a single episode, Donald Bellisario and Don McGill both made the decision not to re-shoot the story with Sasha Alexander's character of Kate Todd, and to leave Vivian Blackadder in the episode.
The result was that the pilot was condensed from two one hour episodes down into a single hour long episode entitled NCIS: The Beginning (episode), which aired on October 21st 2003 as the fifth episode of the first season.
When NCIS went into regular production, it was called "NAVY CIS" which was later dropped, resulting in the series being named "NCIS".
- NCIS Season 1 aired alongside JAG Season 9.
