it is beginning to look that way. The fact that the plane could turn around and land implies that the hijackers were not in full control.
Total speculation: this will be blamed on three immigrants who will be referred to as "asylum seekers" and authorities will deny that there is anything remotely "terroristic" about the incident. There will be some crazy story about the men wanting the plane to take them to Norway or some other non-threatening locale.
Move along, nothing to see.
