My Dad retired after flying the L1011 for at least 15 years. Loved it. Of all the types he flew, he said his favorites were the DC-6 and L1011. Watching the Direct Lift system fly a coupled approach was fascinating. Plus I know for a fact you can fit about 7 folks in a 1011 cockpit easily. We had that many at times on his retirement flight. Even my wife got to sit on the jump seat. Loved those huge windows too.

When the super-stretched 737s came out, I used to call them Low-rider 757s,

As a pax on the tail end of their run. Delta had some sort of airlift contract that guaranteed x number of seats to be paid for. So the Friday night JFK to FRA would go even if it had 30 people on it. I do remember they had a 'middle middle seat' in the center block. 5 in a row :-0

I would sit there thinking, compressor stall, compressor stall, compressor stall.


What was the cause for the heightened concern for compressor stall?


My over-worry about extreme angle of attack and then choke on a bird maybe in that first 1000-1500 feet. Hey, I didn't say it was rational..... :crazy:

And I had the stalls happen twice prior to that in Delta 727's. I was, shall we say, sensitized.

Funny story: 727 out of TPA to DAL. Steep climb out, loud banging compressor stall in number two (I was sitting in the back). The lady next to me put a death trip on me and after we got turned back the Delta captain came on the PA to update us. VERY shaky, hesitant voice but he got it all out. He ended the announcement with, "I just want to reassure you that we take every safety precaution here at Western Airlines". LOL It must have been pretty soon after that particular merger.

There is a Delta DC-7 out in the AZ desert that hopefully will be making its way to ATL on a ferry permit and someday make it over to the Delta museum.

Brings back both fond and sad memories, flew the -1,-250, -500. As the expression went, the Tristar was way ahead of its time.
Probably one of the most notorious maintenance nuisances was the multiplex entertainment system. Most senior F/As and FEs were quite accomplished at trouble shooting it.
Before digitally transmitted FIRM codes, multiple mechanics would greet the flights ready to pounce on any number of issues to ensure an on time departure.
New unofficial acronyms were coined “ Pod Nod “ and “ Shing Ling “ relating to the Rolls Royce RB 211
We had the unfortunate and solemn experience of being Flt 191 the next day into DFW after the crash (8/02/1985) carrying all the family members of the deceased from FLL. Seeing the charred remains of the tail section was quite sobering.
Coordinating with the controllers and as much as possible, we made a wide visual pattern to land on the West side of the airport away from the crash site. May they Rest In Peace.

I’ve done LAX-HNL in a 739er and a 753. No comparison, the 75 wins hands down, and I was in Delta’s “comfort plus” on the 739er and United’s economy on the 753.

Economy in United’s 10 abreast 772 is a nightmare...got stuck on that on HNL-DEN. DL’s 764 was great from HNL-ATL in comfort plus.

Sioux City was a DC-10, not a L1011.

A friend was a senior maintenance tech at Delta. He said the 1011 was the best design he ever worked on, way superior to the DC10.

1011 cost significantly more than dc10. 1011 had 4 hydraulics and a back up stab trim. The 10 had 3 I think with no back up stab trim, a crappy floor, an outward opening cargo door. The door engineers all but predicted that it’s failure would result in floor collapse and loss of hydraulics.

One thing the 737 (ng models and up) has over the 757 is refueling rate. Numbers I'm going to state are based off 40psi. 757s built before 1993 will only take fuel at 170gpm into the wings (both wings combined). After 1993 it's up to 270gpm wings. No one I've spoken to about it knows why. Center tank refueling rate is same and I can't remember that number but it is a lot faster than the wings.

The 737ng will take fuel at 280gpm into the wings and with center tank open with wings 450gpm total -which is the max any hydrant truck should flow. A tanker will pump faster than anything on a hydrant system. I've fueled 737s going to JFK from PHX in 15min. A 757 built before 1993 on same route is going to take 30min minimum to fuel. Big difference if you have 3-4 aircraft waiting for fuel.

And for comparison. A320 series is 220gpm (110gpm each) into the wings and 270gpm with center open. Center will take 90gpm by itself. A321 has a faster rate but I cant remember numbers. It's been 8 years.

That’s what I said if u read it carefully

I flew the 737 (including the Max) for 30 months, and then transitioned to the 757 six months ago. And I'm probably the only airline pilot in history that really isn't over the moon with the 757.

Lots of ergonomics deficiencies that have me shaking my head. Yeah, I realize it was designed in the 1979's. It shows.

A major problem for me is the lack of a decent intercom. As a result, the pilots have to talk cross-cockpit over the roar of the engine, vent, and wind noise. It's easier to talk to the other pilot in the 1940 J-3 that I fly using the portable battery-powered intercom system that we use. It's just amazing to me that in this day of focus on critical comm, CRM, safety and the like, that this hasn't been upgraded on the 757 fleet. I've been on flights with soft-spoken captains where I literally asked them 20+ times to "say again?" And frankly, it's just a lot less fatiguing to have good noise-cancelling headset on rather than lots of ambient noise for 6+ hours. A good intercom is what I miss the most about the 737.

Since 99.44% of the 757 pilots don't wear a full headset... and most takeoff the mandatory earpiece above FL180 and go to speaker... I'm guessing they will have significant hearing loss after 10 years flying it. Cockpit noise runs >80 db.

BTW, the 757 is by far one of the easiest aircraft to land that I've ever flown. It's really hard to not look good when you touch down. So I got that going for me... ... which is nice.

I don't know if you're the only one, but I'm betting it's a very small club. Favoring a 737 (any variant) over a 757 because of the intercom system is like favoring a Cherokee 140 over a SuperCub because the seats are more comfortable in the Cherokee.

I've got about 17,000 hours in 737-200, 300, 500, 700.

The 200 was a simple, rugged workhorse that was the most dependable machine I ever flew.

I thought it was the best airplane ever built until I flew a Falcon.

Haha! Yeah... I get it. I simply didn't want to bore everyone with my laundry list of items that make it less than stellar for me.

Sure, it's probably the best looking airliner out there.

However, when it comes to "flying it like an airliner", I can't tell much of a difference since my goal is to make turns and climbs/descents as imperceptible to the passengers as I did on the 737.

If I could go out and fly my airshow routine with it, that might be a different matter. But it's not like I really get to max perform the roll rate and climb capability when I'm flying it in my real job. From that perspective, a 15 deg bank in a 757 is about the same as a 737.

737-900 was more challenging to really get a great landing... especially on short runways.

Much higher fuel flows than the 737 Max... by a lot.

But at this point, I can't imagine sitting in that noisy and uncomfortable cockpit for 14 days a month, for the next 5+ years.
