In the slot,
If the pilots involved in SQ6, where lives were lost and a jumbo was destroyed, did not get charged or even imprisioned, why would these pilots think that a MINOR incident would land them in gaol.
I think it was probably just a case of thinking that everything is ok now, so we might as well continue to home base.
Whether that was right or wrong is obviously easily debated now. With 20/20 hindsight, everything was ok.
I would imagine that the attitudes that many of the anti-SQ protagonists have are based on a culture of SQ past not SQ present. Lessons are being learnt and slowly applied.
