An air bag that could prevent people from falling off balconies and into the street has been purchased by an aerospace company.

The $6 million purchase of the air bag from BAE Systems Inc. by Aerojet Rocketdyne is the largest sale in the company’s history.

The air bag is the latest in a line of air bags that can be attached to elevators, escalators, elevators and stairwells to prevent people who are trying to leave their homes from falling.

The first one, the AirBag 2, was approved by the Federal Aviation Administration in 2009.

It is designed to prevent someone from falling from a height of about 60 feet.

The second one, called AirBags 3, is intended to prevent pedestrians from falling down the stairs.

The AirBars are designed to be installed by an elevator operator or by a person who is on the ground and needs to remove the airbag.

The company says the new one will be used on a larger scale.
