| Irving Waaland and fellow top Northrop engineers discussed B-2 design and testing at technical conferences. |
| Last month, the Herald Tribune newspaper ran a full-page colour advert for Northrop Grumman, the makers of the stealth bomber and one of the world's big arms manufacturers. |
| They had received a contract to build two Curtiss HS2L flying boats from the US Navy and they needed the help of Northrop. |
| The language was not changed until Northrop Grumman undertook to build the aircraft in Palmdale. |
| For example, in discussing ionized plasma boundary layer control, a certain paper by engineers at Northrop is mentioned. |
| Northrop would go on to operate several of his own companies and was, of course, the main proponent behind the flying wing concept. |
