Did You Know?


Captain Lorca's ship in the opening of the episode is the ISS Buran (NCC-1422) The Buran is a Cardenas-class starship in use during the 2250's by the Federation. The USS Yeager participated in Battle of the Binary Stars with the Klingons in 2256. Star Trek: Discovery: Battle at the Binary Stars (2017)

Like the contemporaneous Nimitz-class and the later 23rd century Constellation-class, as well as the 24th century Cheyenne- and Prometheus-classes, this type was noted for being one of the small number of Federation classes that had more than two nacelles. Episodes where these ships are used include; (Star Trek: The Next Generation: The Battle (1987), Star Trek: The Next Generation: The Best of Both Worlds (1990), Star Trek: The Next Generation: The Best of Both Worlds: Part II (1990) and Star Trek: Voyager: Message in a Bottle (1998)).

The longest set up in TV history?
30 January 2018 | by GraXXoRSee all my reviews

My goodness, the AU plot was a doozy.. Tightly scripted, edge of seat and even occasionally, dare I say, buttock clenchingly tense.

13 episodes led to this point... Like an X marks the spot. If you watch the series again, you can see the signs and the hints... Lorca, the UPPITY Klingons, the Mycelium network...

This epsiode was pure unadulterated Star Trek pulled into the ... ahem... 21st century...

Noble battles of morals against the darkness, selfless acts of bravery... Comeuppance and of course occasional moments technobabble to show that some are cleverer than us...

Not to mention an epic warp to end all warps!!!!

Surely now, for all those naysayers, Ladies and Gentlemen, it would time for all to acknowledge that THIS IS STAR TREK.

If you haven't watched it yet, this is pretty much as good as it gets!!!
