Ahhhhh the old “here, there” problem.
I had that problem once with my “Beer over the internet” device. (I'm still working on it guys, relax)..
One day I decided on fresh eggs for breakfast instead of cereal, when I opened the eggs they had 3 shells (one inside the other), I looked back at the chickens and they shrugged, I then went and checked the digression loop in the internet transfer device and found a ton of Tachyons all piled up in one corner, (I installed a drain) now those of you that may be in the know, will understand that Tachyons and Dark Matter don’t mix, I found out that I had been stuck in a time loop and the chickens had laid that same eggs 3 times, no wonder they were mad at me.
So they (the government) need to know that when you get closer to C then things outside the craft slow down, so on ground radar what should be “here” is really “there”, last time I had a problem like that I blew a hole in Siberia in 1908, found out about it in 1899 due to time/space displacement, I sent a letter but no one replied.
