I like the idea of gliders towed behind C-47s. The player would fly the c-47 and the glider would function essentially as a drone behind the goon. The player could then switch to the glider position for release. If it was solely operated by one player, the goon would continue on level for a time before blowing up once it gets out of drone distance, or a second player could join as a glider pilot while the original player continues on with the goon. Once the glider lands, the player could simply let troops out or commandeer a small vehicle held within the glider's cargo bay.
I suppose the benefit of this would be a very short required landing zone, maybe a short icon range due to it not having a noisy engine.
