I was shocked to find that there were over a half a dozen occurrences of foam strikes recorded. So, we turned that in into the investigation board. 1983 was the first bipod ramp foam loss. 1990, 1992, 92 again, 1994. As well as those bigger pieces, we saw small pieces of foam fall away all the time. What we call popcorning. When popcorn pops, it pops up and comes out and so thats what we call it, popcorning. They werent very big so youre not talking about much damage to the tiles. And so, it had become the norm at nasa. This mantra its only foam, its only foam
