"Taking Flight" is the ninth episode of season two and the twenty-second episode overall of the animated children's series The Magic School Bus. It originally aired on November 4th, 1995.
Wanda and Tim have built a model airplane together ("based on Wanda's dream and idea") for a model air show. Ms. Frizzle has arrived via glider and decides to shrink the class, who discuss wings and thin air, so they can go flying in it. Tim, Phoebe, and Liz stay on the ground to operate the remote control and the plane takes off in the air. Phoebe gets a hold of the remote control and pushes the right lever down, causing the plane to tilt up. Dorothy Ann reads in her book that when the plane's nose tip up and slims down, it is known as a stall. Phoebe pulls the plane up just in time to keep it from crashing. Unfortunately, Tim trips over a pair of binoculars, which causes him to drop the remote control and it gets smashed to the ground as the plane continues flying uncontrollably.
Tim, Phoebe and Liz enter the bus and Liz transforms the bus into a plane. Unfortunately, there is no air moving past the wings. So it can't fly. Meanwhile, Wanda is left steering the plane, which suddenly drops due to Ralphie impetuously turning a lever attached to the side down, which causes the wings to unlock. The rest of the class put the wings back together and Ralphie locks them up again as the plane regains altitude. The class learn that moving thin air is what's holding up the wings.
Meanwhile, Tim, Phoebe, and Liz try to turn the bus into different airplanes and transforms it with ten wings. But since it is too heavy, the air wouldn't hold it up. The class in the model airplane continue to fly through the air and the propeller stops turning. D.A. reads in her book that the propeller keeps the plane moving forward, which slows the plane down as it eventually crashes into a tree.
Meanwhile, the bus transforms into a biplane and the bus finally gains enough altitude to fly in the air. When the biplane-transformed bus is about to crash to city hall, Liz transforms it into an airplane and it flies higher to the sky. The class in the model plane are now stuck onto a tree. The class learns that air moving across the wings is what made the model plane fly before and that the moving air causes its lift. When a bald eagle lands on top of the tree branch, Wanda suggests that the class should use the eagle to tell them to fly back up in the air. Arnold states that birds flap their wings in order to stay in the air and Ms. Frizzle gives the class an idea to pedal to make the propeller turn.
While Tim and Phoebe continue to drive the plane-transformed bus, the class use the eagle to get them back in air by tying one end of a rope to the plane and the other end on the eagle's talons as it flies in the air. The class pedal until the propeller finally spins as Arnold unties the rope, only to end up flying along with the eagle.
As Arnold continues to hang onto the rope, he climbs on top of the eagle and takes a ride. He notices its tail moving back in forth through the wind and uses it to steer to the flying model airplane. Wanda grabs the rope and Arnold slides down and onto the airplane as the eagle flies away. The class continues to pedal, only for the plane to go out of control. So Arnold reluctantly steers the plane and the plane ends up in the model air show, as well as the bus. Liz transforms the bus into a bigger plane and the class lands onto the bus.
Later, at the air show, Wanda explains the physics of flight and she and Tim win the trophy, which they share with the rest of the class. Ms. Frizzle then concludes, "Sometimes, you have to do the wrong stuff to find out what the right stuff really is" as Liz is seen taking a ride on the model airplane.
- A technicolor version of Wanda's plane is shown in a split-second shot at the beginning.
- This is the first time Tim accidentally breaks something, the second is in Sees Stars.
