Tarrant:
[as the surface of the planet Terminal is being rocked by earthquakes and volcanic eruptions] All pilot systems are green. Count is two minutes and running. Better strap down tight, I haven't lifted these into orbit too often.

Dayna:

Vila:
When was that?

Tarrant:
...in about one minute and forty five seconds.

Avon:
If we last that long.
