The DC-3 got up to about 4,000-4,500 by war's end didn't it ?

Still lot's of 722s around, but they're being chewed up in boneyards at ever increasing pace. Their fuel burn is about 50% higher than a 733.

I worked out once though that their block hour cost was still lower than a 733 because of it's quicker flight times reducing the maintenance and labour cost.

Sounds like water ingestion flamed out the engines.

Really now. I would think the lack of fuel - as mentioned earlier might have had more to do with the flameout.....

Outstsnding pilots, and lucky ones
 
Flew the 3 seats in 727-100 and 200s... long ago.
Was definitely a great plane. My first "big airplane". Was like a flying "sports car".
No VMCG (is below V1) - V1 = VR in a 727...
Some are only 160,000 lbs TOGW (JT8D-7) but some can be 205,000 lbs with JT8D-17R power.
But is an airplane that can get you into troubles. Too easy to handle. You get complacent.

One thing critical about 727 is the tail mounted engines.
In icing conditions, anything on your fuselage or wings may be ingested.
On the 727, when having a big black cloud ahead, you put all anti-ice systems ON.
No de-icing... it is ANTI-ICING, and before entering icing conditions.
In addition, rear mounted engines are subject of inlet upsets at high AofA.
So when in doubt, IGN comes on FIRST, then anti-ice (all of it).
xxx
I remember a few takeoffs, heavy rain, deep water puddles with lots of water ingestion.
Engines probably quit at times, fraction of a second, to relight immediately.
So, the scenario of engines quitting "because of water" is not valid.
They would relight immediately. I said "immediately"... provided IGN is ON.
xxx
Three engines that quit together (no coughs), according to passengers, means "out of fuel"...
Let us not jump to conclusions yet. Will be a few weeks... But I think of "no more fuel"...
xxx
One think is certain, the LAB pilots are highly qualified. I know a few.
Many pilots in these countries, know how to handle high elevations and mountain passes.
LAB, Faucett (now bankrupt), Avianca, Ecuatoriana pilots are among these experts.
I trust them more than "flatland pilots" when it comes to flying in that part of the world.
Got to observe with Avianca guys to Bogota and Cali as a guest of their training department.
They showed me a few local things and techniques this old fart did not know.

Happy contrails - These guys got lucky indeed.

Fedex still operates 107 of them. I believe all the -100's are gone though.

Hell of a freighter. Mach .85, legs as long as from Memphis to the west coast, reliable and fun to fly. We are slowly replacing them with 757's, but the current plan is to have them around through 2012 at least.....

Looks like a lucky year for airline pax. It is worth remembering,perhaps, that even had they screwed up on the aircraft management side, it is ALWAYS good piloting that lets you walk away in the end [combined, of course, with luck]

per Kiwiguy:

The DC-3 got up to about 4,000-4,500 by war's end didn't it ?
I believe the total was 10 or 11 thousand commercial & mil. DC-3s, not counting Russian & Japanese copies.

BelArgUSA disputes this hypothesis, but rain & severe turbulence brought down a Southern DC-9 (also JT8D's) in 1977 outside KATL.

Once again thank you to BelArgUSA for sharing facts and personal experience without rhetoric.
And a special appreciation for giving credit to the skills of local pilots, that are often put down by some "knowitall".

I'm really happy that they made it!

I tend to recall that the hail that cracked their windshields and FODed out their engines also had a little to do with it...

In a bit of sad irony, the F/O that was badly burned in that Challenger crash (Colorado, on takeoff, the one that killed the son of NBC's Dick Ebersol and Susan St. James) a few winters back lost both his parents in the Southern 242 crash mentioned above...

Takeoff from a high altitude airport, weight restricted (ie not 'full' tanks), fly to destination, G/A, fly to alternate, and crash one hour(news report) after divert started?

If I was a betting man I'd bet the tanks were empty. (BA 038 was different, it was at completion of a normal flight, so fuel starvation would not be an anticipated problem)

bear11 11th Feb 2008 09:41

Yup, local sources confirm that flying a full load on that route = not enough fuel.

MrNosy2 11th Feb 2008 09:58

Lies, damn lies and statistics!

727 'hull losses' - defined as not repaired and returned to operation following substantial damage.

Including LAB :- 89 operational losses (Annex 13 definition) excluding deliberate acts of violence.
or 94 operational losses including deliberate acts of violence
or 108 operational and non-operational losses including acts of violence - take your pick.

Note a number of these 'hull losses' (as defined) come about because the aircraft are not worth much due to their age and become insurance constructive total losses after suffering relatively little damage but still meeting definition of 'substantial'.

'Hull loss' is not a good measure of safety.
