A spider infestation caused delays for five flights out of KCI on Saturday.
OLATHE, Kan. - The FAA believes it now knows how many flights at KCI were delayed abruptly on Saturday afternoon due to spiders.
There may have been as many as five flights delayed about 15 minutes after air traffic controllers were bombarded with an infestation of spiders.
Three employees were bitten by the spiders last week at the Air Traffic Control Center in Olathe, Kan., which controls the air space around Kansas City.
On Saturday, air traffic controllers had to evacuate and moved to another area of the building.
Exterminators found a spider's nest egg that had likely hatched.
"You're talking in some spider cases up to 400 and in large breeds, you're talking 1000's from one mom," CJ Workman with Schendel Pest Control said.
The FAA has not said what kind of spider it was but said no travelers were ever in danger.
