SpaceX SN4 Has Exploded

SpaceX Starship prototype SN4 has exploded after a static fire.

SpaceX is building these prototypes at a rate of two every month. Each destroyed prototype only causes a two week delay.

SpaceX expects to need 20 prototypes before they have a commercial vehicle finalized. Hopefully SN5 will finally have the first hop and SN6 or SN7 will fly to 20 kilometers.
