The DC-10’s air speed during drops is normally 278 km/h (150 knots) at about 200-250 ft.

The flow rate from the tanks is controlled by using the doors and adjusting the amount that they are opened. This is controlled by a computerized processor with programmed settings for achieving different coverage levels as dialed up on the tank controls. There are eight standard coverage level settings (1–8) on the control panel.
