How fast did satellite-tracked Loon #15746 fly? That's what Kevin Kenow wondered. After he received locations for a couple of intervals as the loon departed Lake Michigan, Kevin found out. "With a few assumptions about take-off location and accuracy of the fixes, I was able to calculate the flight speed of the bird." Now it's your turn to try! Kevin sent the information below. Take a look:
