Captain Elizabeth A. Okoreeh-Baah spent the first five and a half years of her career in the Marine Corps as a CH-46E Sea Knight pilot, but when Marine Medium Helicopter Squadron-263 began transitioning to the Osprey Program while she was stationed there, she became one of the first female pilots to begin training on the controls of the tiltrotor aircraft.
. . .
Shes going to go a long way because she never quits. She can succeed at anything she puts her mind to, said Okoreeh-Baahs father, Isaac K. Okoreeh-Baah Sr., a native of Ghana, North Africa. She gets that from me, I think.
The controversial Osprey is supposed to take off like a helicopter and then fly like an airplane by tilting its huge propellers forward.
Here's some cool video of the Osprey in action.
Before the Osprey, there was always a trade off between fixed wing aircraft and helicopters. The spinning blades of a helicopter make it inherently slower than a regular airplane, with a shorter range and a lower top altitude. But fixed wings need a runway. The Osprey gives you get the best of both worlds: the speed, range and ceiling of an airplane, plus the vertical take-off and hovering capability of a helicopter. The V-22 is designed to replace the big dual rotor CH-46 Sea Knight, which has been around since 1960.
The Osprey is controversial because the military spent a lot of money on it and then it started crashing. A lot. There was a time when the DoD wanted to cancel the program. All I know is when I tried flying my dad's computer game Osprey, I kept crashing it. So I've not always been a fan of the plane (or helicopter, or whatever).
The 1986 estimated cost of a single V-22 was about $24 million with a projected 923 to be built. The first Bush administration cancelled the project in April 1989, by which time the cost of a single craft was estimated at $35 million. However, Congress continued to allocate funding for the program in a November 1989 authorization. Throughout Secretary of Defense Richard B. Cheneys tenure, he and Congress wrestled over the question of the V-22 as he felt the project would cost more than the amount appropriated. Eventually he relented, proposing that $1.5 billion be spent in fiscal years 1992 and 1993 to develop the project. The arrival of the Clinton administration into the White House in 1992 provided new support for the program.One of the crashes was caused by something called "vortex ring state," which happens when a helicopter descends through its own air turbulence. To correct this, Osprey pilots are supposed to descend slowly, although some say that Ospreys should be able to descend faster than conventional helicopters.
Osprey crashes have resulted in 30 deaths. No one died in a June 11, 1991, Osprey crash, but a crash July 20, 1992, in Virginia killed three Marines and four civilians. The Osprey was grounded for 11 months after this crash. A crash in Arizona April 8, 2000, killed 19 Marines, grounding the aircraft for two months. Another crash in North Carolina Dec. 11 of the same year killed four Marines. After the December crash, the Osprey was grounded until May 29, 2002.
Supposedly all the bugs have been worked out. So I'll keep my fingers crossed, and hope that the Osprey lives up to its promise.
