Al-Khalifa pushed the starter and the boring machine roared to life.

After considerable agitation and a lot of standing around, the machine finally roared to life.

As the machine roared past, lights blinked suddenly from a parked coupe.

As the machine roared in on them, they began to abandon ship.

The machine roared to life and settled into an idle.

While the machine roared, Harry gazed at the heavens.

O'Rourke tried the pedal again and the machine roared to life.
