(CBS News) Prosecutors want JetBlue pilot Clayton Osbon to undergo a medical exam to find out if he is competent to stand trial.
In a motion filed late Monday, the government suggested Osbon's midair meltdown last week may have been triggered by a mental illness.
Now, a judge has ordered the pilot be evaluated in a prison hospital to determine if he is "presently suffering from a mental disease or defect rendering him mentally incompetent".
The judge, in Amarillo, Texas, officially cancelled a detention hearing scheduled for Thursday and set another hearing for Monday, April 9.
The doctors must also decide whether he "is unable to understand the nature and consequences of the proceedings against him."
The delay in court proceedings comes as CBS News has obtained new video of Osbon on JetBlue flight 191 taken just before his breakdown.
Tony Antolino, who shot the video on his phone when he noticed Osbon had left the cockpit abruptly and began acting strangely, said it was clear to him quickly that the pilot, and the situation, were at risk of "completely coming apart."
In the video, Osbon can be seen talking with JetBlue co-workers and drinking water. At one point a flight attendant walks away and Osbon reaches out to her.
"I at least wanted something so that, God forbid the phone was found in a field somewhere, maybe there would be some tip, some hint for someone to say ok, hey, what was going on here," Antolino tells CBS News.
Just moments after the images were taken, the in-flight crisis erupted.
Passengers, at the request of the flight crew, eventually tackled Osbon.
Osbon, who has already spent six days in an Amarillo hospital and three days in jail, has entered no plea to the charge that he interfered with a flight crew.
His wife says Osbon never intended to cause harm.
There is a chance that if doctors find he is not capable of standing trial, prosecutors may eventually drop the charges.
Usually it's the defense which requests a mental examination, notes CBS News legal analyst Jack Ford, but in this case, the prosecution seems eager to get the issue of Osbon's mental state cleared up before his fate is turned over to a court - if it ever is.
