TAL.  Trans-Atlantic Landing.  Dakar is no longer on the list, at least 
partially because the government of Senegal didn't provide proper security
for the equipment which was left over there (i.e., it got ripped off).
Marrakech, Morocco is the African TAL site.
Rota isn't used because some people didn't like the shape of the runway.
Zaragoza, Spain is the northern TAL site.

> AOA -- Abort to Orbit (not sure where the a comes from)

AOA is abort once around, i.e. land at Edwards on the first pass.
ATO is abort to orbit.  That means achieve a stable orbit despite
some failure which prevents continuation of the mission.
