The first report came in around 6:30pm Tuesday, according to the FAA, when United Flight 1523, a B737, reported that the cockpit was illuminated by a green laser at around 6,000 feet as it approached Runway 27 at IAH.
No injuries were reported and the flight landed without incident.
At around the same time, the FAA says the pilot of an Atlantic Southeast Regional jet departing from IAH reported a similar laser incident. There were no injuries reported.
According to the FAA, from January to June of this year, there have been more than 30 reports of laser events at Bush Intercontinental Airport.
The FAA says on its website that shining a laser into the cockpit of an aircraft is a serious safety risk. Many high-powered lasers can completely incapacitate pilots who are trying to fly fly safely.
The maximum civil penalty the FAA can impose on an individual for violating the agency's regulations is $11,000 per violation.
The airport with the most laser events nationwide is LAX.
