Space Station and Shuttles

Another foam piece knocking out another chunk of tiles! What are our astronauts, guinea pigs for the space industry?
Just how many times do we put up with such garbage designs, and worse yet, allowing them to fly? Time after time---foam off and into something!
ANOTHER administration ignorance! (they have coined a new word). (meaning to ignore- not ignorance).
Oil and Halliburton is all that counts!
