Can anyone translate?

so lucky no one was killed,how many times does this happen while unqualified people blow with air ? lots , they were just lucky no one was killed.

I personally think what happen should of been a crime. That operator should get fined or put in jail for a month. Something.

These guys are from Bulgaria. It is funny they said and I quote. 

that guy in the grey sweaetshirt.....man was he lucky!
