Unbelievable. I'd like to find out how long those guys were inadvertant IMC and what the pilot was doing to react to the problem.

For the young guys out there, rules for Inadvertant IMC.

1. Don't go inadvertant IMC
2. If you do go inadvertant IMC quickly realize that it is better to be alive than macho.
3. Climb as fast as you can, declare an emergency, and get vectors to the nearest airport or an IFR clearance to your destination.

If any amatures are out there trying to do formation flying every brief needs to include an IIMC procedure, to include which way the aircraft are breaking and to what altitude to avoid hitting each other, and an emergency safe altitude. Even if your departure airport is SKC P6SM.
