Roger Fuller, a former police sergeant, has developed a device to help airline crews subdue violent passengers. This is no joke. When violence erupts at 30,000 feet, passengers and crew can't dial 911. Airline crews are not properly trained to subdue in-flight attackers. Most flight attendants are not physically equipped for the challenge.
Pilots are less willing to abandon two-person cockpits and risk injury while settling disputes.
Bring on the Body Restraint Package. Employing a hodgepodge of handcuffs and restraints, the BRP is designed to lock down aggressors by clamping them to their seat. When a passenger goes ballistic at 30,000 feet, crew members would approach the offender from behind and lasso him like a rodeo steer, using the strap attached at the end of the upper-body restraint. When the restraint is pulled tight, the offender is effectively immobilized. For total lock-down, handcuffs and additional devices can be engaged.
