Several pieces of debris linked to the missing AirAsia jetliner were spotted floating in the Java Sea off Borneo on Tuesday.

The crew of an Indonesian military aircraft noticed white, red and black objects, including what appears to be an emergency slide, a plane door and a life jacket, about 105 miles south of Pangkalan Bun, AFP reported.

Indonesia National Search and Rescue has dispatched at least one helicopter to pick up the items, which will be taken to the agency’s coordination post.

The discovery came as new documents showed the fate of the doomed jetliner may be tied to a crucial two-minute delay in letting its pilot climb to a higher altitude.

A transcript released Monday of the final communication between air traffic control and the pilot of AirAsia Flight QZ 8501 early Sunday local time reveals a calm request to redirect the plane and then to allow it to climb to avoid a storm.

Air traffic control couldn’t say yes immediately because six other planes were crowding the higher airspace, forcing Flight QZ 8501 to remain at a lower altitude, the transcript reveals.

By the time the pilot was given the OK two minutes later, it was apparently too late — there was no response from the cockpit.

Indonesia’s state navigation operator said late Monday that the Airbus 320-200’s pilot, Capt. Iriyanto, who goes by one name, had requested permission to turn left to avoid a storm. That request was granted and the plane turned left for seven miles.

The captain then sent a message at 6:12 a.m. saying, “Request to higher level,” according to AirNav Standards and Safety Director Wisnu Darjono, as quoted by the Jakarta Post.

“Intended to what level?” the controller responded. When Iriyanto said 38,000 feet, he was told to hold off because there were six other planes in that area.

“But when we informed the pilot of the approval at 6:14 a.m., we received no reply,” Darjono said.

Minutes later, the plane disappeared from radar.
