Day 3. Today we learned that the takeoff speed of a SR-71 Blackbird is 241.7mph (210knots). 1knot = 1.15mph. We also learned that the landing speed is 172.6 to 178.4mph (150 to155knots). The runwasy for the Blackbird would have to be over 2 miles long for it to be able to takeoff and land. When the Blackbird lands, it would deploy a parachute to slow it down.
