Oh dearie me, what a stupid git I am.
An unexplored system I had just arrived at in the carrier looked like it might be interesting and normally I would have honked it in the Asp X, but to save having to transfer the 790 tons of tritium back to the carrier cargo hold that the T9 was holding in order to get better carrier fuel consumption, so I could swap ships I thought I might as well launch the T9 and honk it with that one then, if nothing of interest go back to the carrier and do another jump, or if any planets worth landing on put the tritium back in the carrier hold and do the ship swap for the Asp X.
So I launched the T9, honked and lo and behold not only were there two moons with six bios on each, but two planets with icy rings that I could map to see if any tritium hotspot overlaps. Then I went back to the carrier, requested docking permission as usual and waited for the autoland...
But... nothing happened... the reason being because I forgot I had removed the docking computer just before I left the bubble, so I could put another cargo rack on the T9 and get its full 790 tons capacity, so I was now left with attempting to manually land this great cumbersome lump of a ship on the large landing pad I had been allocated:

Now, back in 2015 I never used any kind of docking computer and did all departing and arriving manually, but that was only with smaller ships ie Sidewinder, T6 and Cobra MkIII, but in any case I was now well out of practice. Anyway after several attempts and managing to get very close, I lost all my shields, took hull damage and the 790 tons of tritium I was carrying were automatically jettisoned, never to be seen again.
So eventually I gave up and self destructed the T9, then respawned it back on the carrier...
