Exception to the Rule: Senior Airman (E-4) Below-the-Zone — Air Force unit commanders are authorized to promote 15% of their exemplary airmen first class (E-3) to senior airmen (E-4) six months ahead of the normal TIS. Moving up the Air Force Ranks: The Air Force requires airmen basic ( E-2) to have at least 10 months’ time in grade before they can be promoted to airman first class. In addition, airmen must achieve a 5-skill level, compete in WAPS and complete the Airman Leadership School in-residence before assuming the rank of staff sergeant.

Stay Cool, Stay Warm is a science project that teaches kids how color and temperature are related. At sea level, atmospheric pressure is high, and water boils at 100 °C (212 °F); at higher altitudes it is lower, so water boils at a lower temperature. The trailing car drafts the lead car, uses the pressure reduction to ease its movement through the air, waits for the right curve, mashes the gas and uses the extra power to slingshot ahead for the race victory. While these lifting capacities might not seem like much, airships carry incredibly large volumes of gas — up to hundreds of thousands of cubic feet (thousands of cubic meters). A malfunctioning thermocouple is a frequent cause of gas water heater problems. They are planted in beds with a little gravel or clay and their roots hang down into the water.
