Yikes! Nothing like watching a seemingly routine takeoff out the window of a jet when the engine starts coming apart.

An Airbus A319 plane was traveling down the runway at Santiago-Arturo Merino Benitez Airport in Chile Wednesday when two doors suddenly began flapping in the breeze.

The Flight Safety Foundation explains what happened:

Sky Airline flight H2-112 returned to land at Santiago-Arturo Merino Benitez Airport in Chile after both engine cowl doors of the no. 1 engine broke off during departure.
The Airbus A319 took off from runway 35R at 07:39 hours local time (10:39 UTC). After losing both cowlings on the no.1 CFMI CFM56-5B5/P engine the aircraft circled back and landed safely on runway 35L at 08:04 hours.

This incident is (at least) the 39th event of the loss of an engine cowl door on an Airbus A320-family aircraft. The U.K. AAIB issued several safety recommendations in their July 2015 report of an accident involving Airbus A319 G-EUOE that lost the cowling doors on both engine on departure from London-Heathrow.

Here’s what it looked like when the plane landed:

No one was injured.
