I had only 2 strikes in 20+ years of airline flying.
First on a B737 going into NCL, about 6 miles finals, only moderate Cu around. No warning, big flash, big bang, as we got a strike on the nose just outside the FO's front window. No effect on the aircraft at all. We did find a small burn mark on the nose afterwards.
Second was on a B767, again on the nose, very similar.
For some years I monitored the stats of my (former) employer's fleet, and the rate was about 1 strike per airframe per year, utilisation being about 4000 hr per year.
