HOSTAGE RESCUE SCENARIO and MURPHY AT WAR

anyone out there ever run a seriously thought out hostage scenario?

a "hard" one.

with a player briefing, and forces, then changing the scenario unexpectedly by
cunning GM plan or by a cunning dice chart thought out in advance by the GM
and used to make life interesting.

or by providing the WRONG INFO to the players?

by allowing the players to select their ideal forces for the mission, then
tossing MURPHY at them in all of his glory?

(rescue team aircraft falls out of the sky, vehicle gets creamed on the
freeway enroute to the scene, team leader has a fatal heart attack
DURING THE GO-GO part of the mission, or by hiding  bad guys  among the
hostages?)

how about one of my favorites; space pirates (or terrorists if you universe
does not believe in space pirates) seize a corporate facility on a world or
moonlet with a hostile (as in deadly!) environment outside) and place the
hostages SOMEWHERE on the facility under armed guard or locked down with NO
environmental suits, or maybe suits, but NO HELMETS?

kinda makes a body reluctant just to walk up and blow those airlock doors down
DARTH VADER style, hm?

there are almost limitless possibilities out there.

or how about, a "surprise" assault force (shades of WACO and LITTLE BIG HORN,
among other places!) going after a small force of bad guys only to find out
they are outnumbered, outgunned, and expected?
