Cabin insulation of the Boeing 747-8 airliner Launch and re-entry area intense mechanical stresses on spacecraft, so the power of the insulator is critically crucial; the failure of insulating tiles over the Area Shuttle Columbia caused the shuttle airframe to overheat and break aside during reentry, killing the astronauts on board.
Ecologists have extensive fearful that genetically engineered vegetation could escape from fields and crossbreed with wild family members.
