I was sending 1 LT to each of my colonies.
However although i started them pretty much all at the same time, according to the fleet menu, one of them would be arriving about 3 minutes earlier than the others (all the colonies are in the same system)
Additionally, i was not able to recall that one LT and he did not show up in the overview.
And when the time was up, the did not appear at the colony, but back at the planet i was sending it from.
So it kind of seemed like he was recalled automatically a short time after he started.
