I will point out that the "simple tasks a human servant can do" seems to be tied to the idea of interact with an object, not the movement.
Sage Advice did address this question: In 2002 for the 3E version. It could fly then.
In my games (these are interpretations for the ambiguous spell):
1.) It has to start on the ground - but it can be directed to move into the air and do things in the air - flying, if you will.
2.) It can't attack per se, but it can pull the trigger on a crossbow. That is a +0 to hit bonus with disadvantage because it can't target ...
3.) It is invisible, but it is not hidden. This means that although you can't see it, you know it is there.
4.) It can be used to grant you cover. Attacking it requires you to hit AC 10 - but it is an attack at disadvantage because it is invisible.
5.) It is not quiet. It isn't particularly loud either, but it does not have the ability to be stealthy. DC 10 perception check hears it, and I use passive perception a lot.
6.) The spell ends as soon as you give a command that would take the unseen servant more than 60 feet from you - not once it reaches 60 feet. It disappears when it gets the command, not at the end of 60 feet.
7.) It has a +0 perception, effectively, so it may not be able to hear or see a certain prompt for action. I use the same requirement for Magic Mouth triggers - it is entirely possible the spell won't recognize a trigger because it does not see/hear/smell/feel/taste it. You might tell the Unseen Servant to ring a bell if a creature enters the area - but a stealthy creature can easily sneak by it.
