The moment when the kraken attacks... Your massive ship of 5000000 parts when its in a very low orbit around Kerbol, blowing it into every individual piece, blocking out Kerbol (or at least preventing solar panels from working) and you can't clean it up because a glitch happens where your never allowed to end flight on debris and when you try to use a ship there's soo much debris that it forms an entirly solid ring and every ship only adds to it, and whenever you use rtgs the kraken attacks again so you can do nothing but watch your space program slowly die painfully... DUN DUN DUN!!! Obviously not gunna happen but still a funny story XD
