I can picture it now...
Each chaff "bomb" would fall to the ground at the same rate as a parachute.. and it would show up as 1 enemy a/c in the bar and dot dar.
So we can get 2 lancs at 30k with their 50 -chaff bombs dropping one every minute... and making every defender in an enemy country up to defend their HQ from the HORDE of enemy a/c coming in... they get up there and see only 2 lancs. And lotta chaff.
Meanwhile, they lose all their front fields.
SWEET.
