And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.

Supersonic
Falcon X goes supersonic
Shock waves as an Atlas rocket breaks the sound barrier.
aerodynamic shield of the payload is larger in diameter than the booster upper stage. the step down in size below the payload creates an area of lower pressure as speed increased and caused water vapor in the air to condense and create a cloud in that area. ain't aerodynamics fun???
