As the US celebrates the 40th anniversary of Apollo 11 this month, a number of interesting things are going on. For one thing, NASA will be getting a new administrator. If Pres Barack Obama's choice is confirmed, it will be a homegrown former NASA astronaut, Charles F. Bolden, Jr. Secondly, even though NASA is not stirring the imagination of would-be employees as it did decades ago, technology overall has become a driving force globally. The third bit of interesting news comes from a timely report from Manpower Inc, which found that engineer is the hardest job to fill in America today. The shortage in the number of engineers is expected to continue well into the future.
