We find is very interesting that we taxi out to the runway and then back to the
terminal. It is even more interesting that the ground crew opens the
engine cowling. It seems the right engine will not start.

After a hour wait, we wonder about the fact we no longer have a visa to enter
Cuba. Fortunately the engine eventually starts and 20 minutes later, we taxi
to the runway and take off. A collective sigh of relief fills the cabin.
