Funny.

It's UGLY, but...
Engineers from American Airlines have closely examined a modified thrust reverser on a Pratt & Whitney JT8D-200 designed by Dugan Kinetics for Boeing MD-80s that could potentially cut fuel burn and reduce noise.
The test aircraft (N789BV) completed functionality and performance testing during 9-12 December at Tucson International Airport, and then flew to American's bases in Tulsa, Oklahoma and Fort Worth, Texas at the carrier's request, says Dugan. American operates around 260 MD-80s, according to Flightglobal's ACAS database.
Dugan has developed a new stow position for the thrust reverser in which the doors are used as an ejector during flight. The new position allows for an increase in thrust while keeping aircraft weight constant.
By mixing ambient airflow with the jet exhaust, thrust is increased and substantial fuel savings is achieved during climb and cruise through use of the EP-80 Ejector/TR. Dugan has previously said the modified thrust reverser could cut fuel burn per flight from 6% to 12%.
The testing included two baseline flights and two flights with the modified thrust reverser on an MD-8. The duration of the test flights was between 3h and 5h.
Dugan says one of the primary purposes of the testing is to fully understand where the ejector is augmenting thrust to determine a definitive number for fuel burn reduction, and it expects to receive that data from flight engineers soon.
The company also expects to obtain a supplemental type certificate covering the EP-80 Ejector/TR during the later half of the first quarter, says Dugan.

Heyas,
Yea, timing is a funny thing.
When I got hired, NWA was just slightly left of center in it's hiring curve. I just barely made my self-imposed deadline of making it to a major by thirty (turned 31 two months later). Yet I was the 2nd to last in class and the youngest was only a month younger than myself. Oldest was 52. Everyone was civvie, except three guys who came from the military via a cargo or other outfit.
The choices were DC-9 or 727 wrench. A few clases after me, the dam broke, and new hires were going everywhere...727, 320, 757 right seat, DC-10 and whale back seat. The 320 and 757 programs were besides themselves because they weren't set up for newbies. By and large, though, it seemed that everyone I met was pushing 30 when they got hired.
A year and change later, when I was working in the sims, I started seeing really young guys pop up. One dude was 24, and had just hit all the milestones just right. There had been some guys hired young back in 95-96, , too, and they were already captains in 2001 on their 30th birthday.
Times change. It's better to be lucky than good, however.

Hey Boog,
I'm right in front of you...DEC'95. We had ONE guy in our class that actually realized the "you'll all be Captains in 5 years" promise. He held it for a total of 4 months. I finally made the check-out in January of '07. Just over 11 years. I feel your pain.

I was a 75/76 FO during the PanAm ingestion. Going through recurrent right after it was announced, some mgt type came down to blow some sunshine up our skirts. Told me I wasn't gonna be a copilot much longer! He was right. Went from middle 76 FO to the panel. I guess I should've asked him to be more specific!
