Answer: When the Magic Kingdom opened its gates on October 1, 1971, there weren't many attractions yet, but new rides were already in the works. The concept and planning for Space Mountain began almost immediately. Rather than foot the entire bill themselves, Disney convinced RCA chairman Robert Sarnoff to sponsor the new attraction. RCA agreed to contribute $10 million to help fund the project. In return, RCA was prominently featured throughout the attraction. A towering sign with RCA's logo was displayed above the attraction's entrance, and guests exited Space Mountain through a post-show display featuring RCA's Colortrak television sets.

What does the "N" in an N95 mask stand for? The N95 respirator is an air-purifying respirator which is certified by the National Institute for Occupational Safety and Health (NIOSH). The various ratings assigned to respirators indicate how well the mask protects against oils and are denoted by the letters N, R, or P. The "N" in an N95 mask stands for “Non-Oil.” According to NIOSH, "respirators are rated "N" if they are not resistant to oil, "R" if somewhat resistant to oil, and "P" if strongly resistant to oil." The number "95" indicates that the mask filters out 95% of airborne particles. Thus, an N95 mask is not resistant to oil and filters out 95% of airborne particles.
