Jordan & Matt were paying attention, but only Josh saw the marshmallow catapult into the air. Oh - Jim was paying attention, too, but not to his own group...

The marshmallow is above Jackie's head, but Taite, Jackie, & Christine all missed it!

Now they look up!

Time for Christine to earn her pay!

T.J. achieves a high arc.

This time Mariah & Danielle are watching!

...watch it begin to rise...

...and watch it drop right back down!

C.J. & Tayler back up as their balloon goes wild!

C.J. laughs as Tayler backs out of the picture to escape their crazy balloon!!

Tayle, Kyle, Nathan, & Jesse are impressed at the height of their flight.

The balloon doesn't go up. Kamila is amused by a different group off-camera, and Sara is visibly upset, while Mallory ponders the situation, looking for a solution.

Sam, Sam, & Rachel watch their balloon drop as it expends the last of its fuel.

...They beat the photographer, anyway!

Chris reaches back...

...steps forward...

...and sends his plane into the 'wild blue yonder'!

Eddie ducks as Jake sends his plane up.

Becki goes for one more flight...

...and nearly knocks herself over to make it a good one!

Sami, Kayla, & Sam try this synchronization one more time.

Sami's plane is gone, Kayla's hooks sharply to her right, and Sam never let go!

Jim sends his plane along ... right out of the frame!

Tyler give the camera a funny look...

...reaches way back...

...and lets it fly!! Mallory's looking quite impressed!

"...Bring the plane forward at a sharp upward angle..."

"...And snap the wrist forward for a long, level flight!"

One of Tayler's less successful early flights, diving straight down.

Scott shows a little power...

...As he fires his plane at a specific target.
