- Because thats not what causes a sonic boom - the sound you're
- hearing when a jet flies past is the edge of a 'cone' of sound
- formed as the air is forced to move around the plane faster than
- it wants to (ie, the speed of sound). This shockwave propagates
- down to ground level, where you hear it as a sonic boom after the
- aircraft has passed overhead - its _not_ just when the plane
- breaks the sound barrier. (Note: this is only a rough explanation
- of the phenomenon, buyers beware.)
-
- I believe in ATWOP there is a reference to a slight 'pop' as a
- firelizard goes between... and thats the only reference I can
- remember _anywhere_ about a sound accompanying the dragon. I
- imagine there is a slight 'whuff' as a dragon vanishes, and a
- dull 'foomp' as the dragon reappears, the air rushing in and
- getting pushed aside respectively.
-
- PS: ATWOP has been out in paperback for over a week now. I
- believe that means we can spoil to our hearts content... readers
- and paranoids beware. :)
