Risk Aversion At Odds With Manned Space Exploration
Several readers including tyghe!! sent in a Popular Mechanics piece analyzing the Augustine Commission's recommendations and NASA itself in terms of a persistent bias towards risk aversion, and arguing that such a bias is fundamentally incompatible with the mission of opening a new frontier. "Rand Simberg, a former aerospace engineer finds the report a little too innocuous. In this analysis, Simberg asks, what happens when we take the risk out of space travel? ... Aerospace pioneer Burt Rutan said a few years ago that if we're not killing people, we're not pushing hard enough. That might sound harsh to people outside the aerospace community but, as Rutan knows, test pilots and astronauts are a breed of people that willingly accepts certain risk in order to be part of great endeavors. They're volunteers and they know what they're getting into."
I'll assume you were repeating something someone else said but next time try a quick internet search before passing it on.
Both missions where Challenger and Columbia were destroyed were launched in January not February.
The launches were 17 not 20 years apart.
They were not launched on the same day. (Challenger launched on Jan 28, 1986, Columbia launched on Jan 16, 2003)

Some of what I say is fact, some is conjecture, the rest I'm just blowing out my ass...you guess.
