	::4. Next question: How long will it take to cover that distance? For that he needs to know the airplane's ground speed and that means getting an accurate handle on what the wind is doing (something he has not been able to do all night). Now that it's daylight he can estimate the wind by watching the wave tops on the ocean or using his drift meter.		::4. Next question: How long will it take to cover that distance?

He, of course, means that they'll reach the line at 19:00. If they're bang on course they'll also reach Howland at 19:00, but Fred has been [[dead reckoning]] all night without a celestial fix. He knows it would be amazing if they are still exactly on course. Amelia doesn't understand the nuance. All she knows is that Fred says ETA 1900.		::5.

"Due to the skip characteristics of 6210 Kilocycles, Earhart’s decision to switch to that frequency effectively shuts off any further reception by Itasca.

			:We do not have a copy of the tape, just the transcript. This is what [[Bellarts]] told [[Long]] in 1973 about the way [[Earhart]] sounded:

			::"Ah, actually her voice...we could here her voice just as easy as I'm hearing yours right now and I'm deaf in one ear now. But I'll tell you, you could hear her voice all over the shack and even outside the shack. you know, real loud and clear. I mean it. She was a woman. We heard her quite a few times, you know, but that last one, I'm telling you, it sounded as if she would have broken out in a scream, it would have sounded normal. She was just about ready to break into tears and go into hysterics. That's exactly the way I'd describe her voice now. I'll never forget it."
