You press the button
As you press the button, all lights dim and together with a honking-alarm a red light now illuminates your cockpit.
This is your computer speaking, we are going to make a crash landing, thank you for relying upon me. We've had plenty of occasions in which you arrogant, cocky space jocks wanted to down your space-crafts themselves, was it not for... oh.. ahem.
In amazement you are looking through the cockpit-window, the planet below you is coming at you dazzlingly fast!
Uhm.. where was I.. oh yeah: FASTEN YOUR SEATBELT!! BRACE YOURSELF!!
With a thump you crash down, glass breaking, your snacks flying through the air.. you wish you did not eat so much as you are now in for a bumpy ride on the planet's surface. The spacecraft bobs and hobs, turns over and comes to a hold.
It is very hot inside the cockpit... maybe you should get out?
