Hello dear friends. Today I’m starting a story that will expand over a few riddles. A series of riddles, if you like 
. This is the first in the series. I hope you will enjoy this riddle, as well as the whole series, and come up with many inventive solutions. Good luck!
“All officers to the holospace room. All officers to the holospace room,” can be heard on all intercoms.
From all around the ship, officers flock to the holospace room.
The captain was waiting there, with the first officer to his right.
“The captain has a very important announcement to make,” says the first officer.
“Thank you, number one,” replies the captain, “this is concerning all of us. Effective immediately, the first officer is in charge of this ship. I’m granting him full authority. You will follow his orders as if they were my own. You will direct all top security questions to him.”
The chief of security steps out of the crowd and says:
“First officer, you are under arrest for attempting to compromise security of this ship. The captain would never give such orders. This captain is obviously a hologram you have programmed as part of your scheme. Where is the real captain?”
As the security chief tries to handcuff the first officer, the cuffs just go through him - he was a hologram.
“What is this new devilry?” asks the security chief, very confused.
Indeed, what has just happened?
Note: Official riddle answer: This Is Not a Drill!

The captain had programmed the hologram of the First Officer as a test for the officers, to see how they would react.
damn, i guess number one was the captain and the captain was number one. in elite of course ( http://en.wikipedia.org/wiki/Elite_(computer_game) )
The captain and the first officer are both holograms. They were put there as a diversion to distract the security officer while the real culprit is elsewhere on the ship carrying out whatever nefarious plan he obviously has in store.
I like Brandon’s answer.
I’m gonna make another guess. The security chief set it all up. He was the one speaking in the intercom luring everybody to the holodeck so he can trap them there in a lockdown in case there was a security breach while his cohorts take over the ship.
