No more comments, except that the planes were going UP AND DOWN at each

Wrong on several counts:
1) The altitude contributes to the GR time dilation
2) SR time dilation depends on the aircraft speed along its up-and-down
   path, not merely on the aircraft's speed relative to the ground.
   (i.e. its "normal" speed, as you put it)

Let us imagine a spaceship traveling up and down along the following
path:

t(s)  x(ls)  y(ls)
0     0.0    0
10    0.1    1
20    0.2    0
30    0.3    1
40    0.4    0
50    0.5    1
60    0.6    0
70    0.7    1
80    0.8    0
90    0.9    1
100   1.0    0

The spaceship's average flight speed will be 0.1005c, while its ground
speed will be 0.01c. That makes a big difference in LT calculations.
