Random Cool info of the day SR-71 Blackbird Could travel about 1/4 the surface of the earth in an hour, if refuled mid flight it could circle the earth in around 6 hours. A top speed of about 980m/s or 3500km/h If it had the ability to have some liquid fuel engines attached it could go into orbit and be anywhere (pretty much) on earth within 2.5hours. (ignoring airframe strength limits etc) en.wikipedia.org/wiki/Lockheed_SR-71_Blackbird
