Too impractical. Extremely hard to manage.
I thought about this concept before, but in actuality, would not work.
Point 1 - The Vehicle would have to be very large:
In order to contain, say 3 jeeps and still look normal, the plane would need to be about 4x the size of the C-130 and the cars would be cramped.
Point 2 - Plane cannot carry cars or other vehicles:
Point 2a - Plane could not move due to defeated purpose:
In order to effectively carry vehicles or people at the same time, GSF's nomount script would have to be used. I'm not positive on this or not, but I believe the Carriers in his pack (with nomount) do not have wheels to power it. A Vehicle this size would have to use wheels to power it otherwise not able to move effectively.
Point 2b - Vehicles could not be carried effectively:
When on one of the Carriers, the vehicles have no problem. They are able to rotate well horizontally as the carrier drives. The vehicle's slow speed makes this possible. However, when in a plane, you are going much faster. The vehicles inside would slide and grind collision boxes inside of it's cargo bay. At high enough speeds, vehicles would start to bounce around inside, causing major collision problems and serious lag. Nevertheless, you cant put collision boxes inside of eachother, so if created unproperly, will not allow vehicles to be carried.
Point 3 - Vehicles could not be loaded inside of the plane:
Animations for a hatch door in the back can be made, but the collision box cannot be animated.
Point 4 - Plane would be impractical and unrealistic:
First of all, the vehicles could simply be too heavy for the plane to carry. Wheeled vehicles could be too heavy for Accleration and change of direction. Say there were vehicles inside, the plane is slow. You add a boost of speed and it is somehow fast enough to fly around, what if it wasn't loaded. It would be unreasonably fast.
