How far the Divorcepidemia can go?

Divorce is a plague of the modern world . It underlies much of modern life boredom. The damage it does to our children and their children and their children's children is immeasurable . It is almost as though we have visited a social plague of biblical proportions on our own with our disregard for marriage , home and family .And we ignore these things.

An alternative approach to space exploration?

As engineers, we need to avoid getting stuck in the same old mindsets and attempting to solve problems in the same way over and over. Sometimes we need to toss out the old way of doing things and take a fresh approach.
Consider the approach that some of the commercial (privately held) space research companies are taking in doing projects, and compare that to NASA's traditional approach. Rather than lift the whole launch vehicle vertically using powerful rocket engines (high stress over a short time frame), they are using a high-altitude aircraft to lift the launch vehicle to 40,000 to 50,000 feet over a longer period of time -- a kinder, gentler approach.
Aircraft are a more mature technology, and statistically more reliable, more environmentally friendly, and less expensive to operate than rocket boosters.
