What You're About to See Is Totally Classified

Agent Simmons: What you're about to see is totally classified.
Keller: Dear God... what is this?
Tom Banachek: We think that when he made his approach over the North Pole our gravitation field screwed up his telemetry and crashed into the ice, probably a few thousand years ago. We shipped him here to this facility in 1934.
Agent Simmons: We call him NBE-1.
Sam Witwicky: Well, sir, I don't mean to correct you on everything you think you know, but, I mean, that's Megatron. He's the leader of the Decepticons.
He's been in cryostasis since 1935. Your great-great-grandfather made one of the greatest discoveries in the history of mankind.
Agent Simmons: Fact is, you're looking at the source of the modern age, the microchip, lasers, spaceflight, cars, all reverse-engineered by studying him. NBE One. That's what we call it.
Keller: And you didn't think that the United States Military might need to know that you're keeping a hostile alien robot frozen in the basement?
Tom Banachek: Until these events we had no credible threats to national security.
Keller: Well, you got one now!

Banachek and Simmons continue the briefing on the transformers by showing them Megatron.
