Yes, that is very true. According to this site:
http://www.lightningsafety.noaa.gov/statistics.htm
The average number of people killed by lightning every year for the past 10 years is 39. That would total about 200 people in the past 5 years.
In the past 5 years (since August, 2006), there have only been 2 crashes in the US that involved fatalities - totaling 99 people. During that period of time, US domestic commercial airlines have carried more than 3,452,640,133 passengers.
99 out of almost 3 1/2 BILLION is 0.0000028%
Crash data is available in a searchable data base here:
