Time will tell over future re-launches unless SpaceX knows something we
don't. Have they run a Merlin to destruction under normal
misdsion parameters,i.e. 1000's of sec. burn time? Lots of LOx.

From hobbyspace.com about the latest Falcon 9 launch:
" A first stage engine shut down prematurely (just before staging) but
had no effect on the mission as the other 8 engines made up the difference.
The booster also failed to make a successful landing on a sea platform.
This was the fifth flight of this booster."
That was after a previous launch attempt aborted due to slightly high
power.
Wonderful demonstration of engine-out fault tolerance, but it does look
like the rocket is showing some wear and tear after 5 flights. What does
this do to their economics if stages need an overhaul/have an increased
chance of loss of vehicle after only 5 flights?
