Yee-haw! Another 47.9 Miles
With help from 3-4 MPH tailwinds, the birds flew 1 hour, 20 minutes farther south into Illinois today. It seems
they have switched into migration mode because they were raring to go and eager to fly. Pilot Richard van Heuvelen
lifted off with a long line of white cranes strung out like a banner off his left wing. It was a near-perfect take-off--except
only 13 birds were behind him. Heather tells what happened: "Two youngsters turned back to the pen right after
launching and another lagged behind, still in the pen. Dan managed to encourage the pair back into the air by temporarily
disguising himself as the swamp monster, but by the time
the pilots realized they did not have all 16 birds with them, it was too late to turn back and attempt to pick
Richard and his 13 birds kept flying, with Joe and Brooke as chase pilots behind. The ground crew hit the road
with 3 cranes riding with them. You can imagine how thrilled the caravan was to catch sight of the birds and planes
overhead as their paths occasionally crossed.
Today's skies were cloudy and the air a cold 34 degrees F-- but even colder aloft! On October 16 we asked you
to journal about why it was colder at high altitudes, which are closer to the sun. Now look back and compare your
answer to this: Sunlight, or solar energy, comes through most of the atmosphere without warming it much. Sunlight
does warm the ground or water when it hits them, however. The warm ground or water then warms the air next to it.
That's why the farther from the ground, the cooler the air usually is.

- If the cranes must fly 1225 miles to the end of the journey, how many miles to go? If they fly about 47 miles
each and every day from now on, what's the soonest date they could reach their winter home?
