So there are secret bases and experiments taken out by many countries on Antarctica πŸ‡¦πŸ‡Ά it’s the coldest place on earth and many none flight zones and you have to have high security clearances to go there. An experiment that was taken with liquid conductor metals. Not the correct term but like Mercury. When it is super cooled it can hover over magnetic field like antigravity. So if there are alien bases hidden in Antarctica πŸ‡¦πŸ‡Ά Or a warp hole it would make perfect sense to be there so they can travel super cool the ship as it would of been cold to travel through space. As space is cold. Then cool of before they go somewhere in the world 🌍 plus it would make sense for crash landing as mistakes happen which might be the cooling of a ship heats up and the crash where ever it maybe??
