In an animation the player takes out his transceiver and shouts
"We need some supplies flown in ASAP! coords 4667x9843"
An awesome looking jet soars trough the sky with an awesome roaring or a sonic boom.
A packagepod falls out of the jet speeding towards the ground quickly and at the last second some counter thrusters ignite and the pod smashes into the ground, and becomes right clickable.
See youtube Halo 2 weapon/ammo pods for more information.
