about 10,000 people are injured on u.s. escalators each year, predominately children under 5 and adults over 65. 3 out of 4 injuries were due to falls on or off escalators. some were fatal. the most common injuries are broken bones, lacerations, lost fingers and/or toes, and strangulation.

although sophisticated crash test dummies and computer modeling play an increasing role in automobile safety, human corpses are still often used in crash tests, especially in testing new safety features. the industry just doesn't like to talk about it.
