I wonder how many successful launches SpaceX has had. I have heard about a lot of failures. If the number of failures is any indication, I would not trust them to launch anything of value.
Are they still using Russian rocket engines? Then...
Rockets from the Falcon 9 family have been launched 44 times over 7 years, resulting in 42 full mission successes (95.5% success rate), one partial success (with primary orbital payload delivery completed, but a secondary payload left in a lower-than-planned orbit), and one failure (with total loss of spacecraft). Additionally, one rocket and payload were destroyed before launch in preparation for an on-pad static fire test. 19 of 24 landing attempts (79%) have succeeded in recovering the rocket's first stage.
