DVD cover.
A good thriller starring Roy Scheider, Warren Oates and Malcolm McDowell.

The cop test pilot, Frank Murphy (Scheider), for an experimental police helicopter, named Blue Thunder, learns
the sinister implications of the new vehicle.

He records an important conversation on the tape during a test flight on Blue Thunder. The bad guys chase to kill him before he can use the evidence to expose them.

I like the sky action. Malcolm McDowell is great as the bad guy. I really dislike him haha.

Just colour pencils.
