Yes it would depend on how long you drove before you stopped and what rpm you were on. I had an oil filter come loose, smoke bellowed out from the bonnet. Stopped her straight away. It was a cold evening at Christmas and I was within 2 miles from home, so neither oil of manifold were warm enough for the oil to ignite!! Very fortunate.

Feared the worst. Replaced filter, filled with oil......all fine. Changed it 5 months later anyway, but no issues. You should be ok.

Despite the naysayer it depends on how you were driving it. Low revs and pootling will mean you have a decent chance of saving it. If you were giving it some I'd be telling you you have had it.
I have to agree completely with Ultra. As I have said before crank bearings are not separated by oil pressure created by the pump. The pump is primarily there to get the oil to the bearings and replace the losses. If a film of oil exists on the bearing surfaces its the relative motion that causes them to separate. When you lose oil pressure it takes a while for the centrifugal effects to fling out the oil including including emptying the crank drillings. Run an engine gently and you can go for miles without damaging anything. I've done it twice ! The first was just to see if the theory lived up to practice. The second 4 years later because I just wanted to get home. With the experience of the first I knew I could. The only repair in both cases was brazing some new drive-lugs on the pumps.
Why would anyone run an engine to destruction ?? !!!

Indeed, nothing to worry about

Trunkz! Really hope the car is ok. Simple error.

I once serviced my old Cagiva Mito 125 and forgot to re-connect the small hose to feed the oil. Tiny little thing. Riding and BOOM engine seized up a bit. Managed to fix it with a top end replacement.

Absolutely. Bench tested it years ago. I forget a lot of the details but we got something like 10hrs on a bench at idle conditions
I can't rememeber if this applies to the Honda but a lot of bearings these days are micro-grooved. Small regular grooves running the circumference of the bearings are there to try and hold as much oil in the bearing and stop it spilling out of the side.

Rag the nuts off it though and it will be fubar'd

Magnetic sump plug arrived from sumo this morning. Does someone know the correct torque figure for the sump plug? I usually do it by hand but will torque it up correctly from now on.

It's 39Nm, always use a new washer and do not overtighten.
You can strip those threads pretty easy.
