Accidentally hitting 'GO' or 'RECALL' on the wrong ship could be painful and we all have been there. To save you the trouble, from now on you can cancel your warp during the initial 5-second charge up and even mid-travel!

To cancel the 5-second warp charge-up, simply tap the X button on your ship, that will abort the journey.

 Cancel Warp  
To cancel a warp in progress, access your Ship Action Panel and tap Emergency Stop. This would drop your ship out in the next system along its route.

 Stop warp  
Safe travels, Commanders!
