Maybe they had an outdoor picnic scheduled.
Bunker busters are for penetration. A thousand feet of rock isn't open to penetration. A cave is built into a mountain. Bunkers are built without that mountain. The most notable bunker busted during Desert Storm was in downtown Baghdad.
The MOAB is designed to over-pressure a cave system, crushing anything inside it with a shock wave. 5,000 psi, IIRC.
