Smudge, Not sure if I had stated before but in late 90s early 2000s the Americans were playing with something similar to the daisy cutter out at YPG. under the guise of a Kistler satellite launch rocket. It was dropped under parachutes then they lit the fires. A UK team from Irvin were out doing the trials some of them stayed and were still there the last time I went in 2011. If you look for the parachute test centre adjacent to Laguna airfield on google maps satellite view the test vehicles are still in the scrap compound.
Pictures exist of an Argentine c130 used as a bomber during the Falklands.
So far as I know we never dropped any such things.
An MSP load of 105 or even 80mm mortar rounds may make a big bang
