Animorphs

Why was everyone panicking about which button Jake and Marco hit? If they hit the wrong one, the could just hit the right one before they got too close to the planet.

The Blade ship started descending when Marco pressed a button. That is not possible in space. There is no gravitational pull so the only thing that could happen is that the ship stops where it is.

While Jake and Marco were figuring out how to start the Blade ship, why didn't the Controllers just board the ship and take them?

It's doubtful that the Kandrona would overheat in seconds. If that were possible, the Yeerks would have put in a lot more cooling equipment.

Why wouldn't Visser Three have the morphing detectors installed on the ship? He knew that he was bringing the "Andalites" onto the ship and that they had small morphs. Wouldn't he take precautions?

For just the 2 Vissers and the 2 Animorphs in the room, Jake and Marco are talking to each other rather loudly considering how quiet and prone to echoes the room is.
