Bommerz!

UPDATED:
re-cropped the pix below.

Bommerz Over Da Sulpher River was a small Games Workshop game that allowed you to play Imperial Guard fighters vs Ork Bommerz. The game scenario based around a river with vital bridges and gun emplacements. The Ork Bommerz would streak down the river and attempt to take them out, while the Imperial Guard player had to defend. The game was fast-paced, wouldn't take more than 30 mins, and was great fun. They were epic-scale fighter planes that you could eventually use in Epic Armageddon (I think you could use them in Epic 40k, but I don't remember for sure).

Here's the Ork Bommerz that I got about 90% complete.




I painted the IG Thunderboltz, but they're only about half-finished.
