Of course two hot air balloons can see each other with a telescope. But, eventually, they can't because the distance is too far and this too many particles are in the way, so you can't see it.
But surely you could bring a light so powerful, or a laser that could penetrate far enough to debunk the curvature of the earth. Or how about a radio signal known to travel a far distance through the air?
In my view, the burden of proof is on you, as the round earth has been sufficiently demonstrated to be true.
So, no matter how bright the light, if it's going through an atmosphere with particles in the air, eventually, there will be too many particles for the light to shine through.
I'm not talking about it traveling to the end of the earth (Ha!), just sufficiently beyond the horizon to demonstrate there is no curve. The distance of the horizon in kilometers = 3.569 times the square root of the antenna height in meters.
Look at how you believe these things you've read without any proof.
The real reason you can't do it is because nobody can do it because the earth is round.
