The Animorphs are on a mission to capture a fallen bug fighter so they have hard proof of the alien invasion. The Yeerks are desperate enough to keep the wreckage secret they actually succeed in fighting back our intrepid youths.
The failure of this bogus mission unfortunately sends an unconcious Cassie on a plane to Australia. There are some mile-high hijinks involving tractor beams that are confusing. Why can't the Visser just authorize shooting down a plane?
Other such questions lead me to seriously doubt Visser Three's decision-making process. Cassie has a bit of fun, though, so that's good.
