I would love to see these pictures.
Even if you would be shown a 1000000 pictures from high altitude flights, you would find excuses to prove your flat earth theory. So before you take a look at any picture that can easily prove you wrong, you need to open your mind's eye. And your little experiment of opening a picture (of the horizon) in paint proves only one thing, like previously mentioned, that the picture WASN'T taken from a high enough altitude.
Btw, have YOU ever flown in an airplane?
Yes, many times. Most of us here have. The few the pretend their high-altitude experiences are unique are simply ignorants.
And as I expected, no one cares to post a picture. I have a feeling that we'll still see people hold to this argument, regardless. And thats sad.
Your turn is coming, pal. In just a few days, we'll have you dining on crow. It might be a good time for your computer to go on the fritz. We do take the FE's challenges, even when they ignore our challenges, seriously. You may want to be careful what battles you want to fight.
Alright, here's the plan, or at least an outline. First, realize that the effect is difficult to detect, so we'll need to gather our evidence carefully, do careful measurements, analyze the data carefully, and reach our conclusions methodically.
Step 1: Design an Access database to hold the data and results. I envision at least three tables: Photo, Measurement, Summary. While the summary table will violate 2NF, I suggest that the complexity of the analysis makes this violation prudent.
Step 2: Develop the database.
Step 3: Develop the process to gather the data (how to select photo and perform the measurements).
Step 3: Populate the input side of the database (photo and measurement).
Step 4: Design a SAS 9.1.3 program using BASE, STAT, and ACCESS.
Step 5: Develop the program (include debugging).
Step 6: Run the program.
Step 7: Publish the results.
