Many people not the similarity to red blood cells.
Ofcourse, that is sort of ridiculous if there really fell 50.000 kilos down, and seeing as how several districts reported this rain it seems really seems to be inlikely to be from a single point source as a plane. Anyway, why no planeparts come raining down? I read an article in Newscientist in which someone suggesting a comet splashed a flock of bats to smithereens, mixing their blood with clouds and letting it rain down over a period of 2 months.
Still ridiculous, as bats dont disintegrate when they die but let wings and other parts fall down too. Also, bloodcells (of any mammal) fall apart in normal water after just minutes, and these bad boys survived years in bottles. That is just not normal. Also they survive temperatures of 300oC, which no earth lifeform has ever been found to survive, and multiply by that temperature.
Speaking of bats. If you can find the column from Dave Barry (perhaps in his book Dave Barry Talks Back it is hilarious.
Cheers!
