美帝现在是军民商三合一
据美国司法部统计，美国民间拥有2亿3千5百多万支枪，几乎是人手一枪。
美帝大概有五十万各种级别的飞行员
As of the end of 2009, in the US, there were an estimated 594,285 active
certificated pilots.[12] This number has been declining gradually over the
past several decades, down from a high of over 827,000 pilots in 1980. The
numbers include:
72,280 student pilots
234 recreational pilots
3,248 sport pilots
211,619 private pilots
125,738 commercial pilots
144,600 airline transport pilots
21,268 glider-only pilots
15,298 rotorcraft-(helicopter)-only pilots
These numbers are based on the highest certifications held by individual
pilots.
There were also 94,863 certified flight instructors (CFIs), and 323,495
pilots overall who held instrument ratings.
An active pilot is defined as one who holds both a pilot certificate and a
valid medical certificate, for certifications that require a medical
certificate. |
