| Before 1914 artillery shells had consisted mainly of shrapnel, whose airbursts were effective in mobile warfare. |
|
| Objects 50 meters across strike Earth every few centuries, causing airbursts that rival the effects of large thermonuclear bombs. |
|
| Thirty miles from the targets, they began seeing the airbursts of radar-controlled antiaircraft artillery. |
|
| The heat and concussive force of the airbursts produced the expected results, instantly engulfing the rebel base in an apocalyptic conflagration. |
|
| I should note that what's important here is the general principle, not the exact numbers, because the equation I'm using was developed for nuclear airbursts. |
|
| But then, dodging airbursts of Archie on the Western Front hadn't exactly been a joyride either. |
