This reminds me of a night that I was assigned a flight scheduled to depart JFK (New York) and fly to MEX (Mexico City), then continue to IAH (Houston).

 

While performing my Captain's pre-flight review of the Maintenance Logbook I noticed that the aircraft was a version of the Boeing 747-200F (the "F" is for freighter) that had 3 ACMs (Air Cycle Machines for air temperature conditioning and cabin pressurization). One ACM was inop and deferred for later maintenance as per normal procedures, but upon further review of the Aircraft Mx Logbook, another ACM had a valve not working correctly and was therefore unreliable. So we had to dispatch the aircraft with only 1 operating ACM.

 

Dispatching with only one source of pressurization was possible and legal, but we were limited to FL200 (nominally 20,000 feet above sea level) as a maximum cruise altitude (obviously for safety reasons).

 

I checked the company generated flight plan and there it was... FL350 for planned cruise altitude. Called dispatch, pointed out the issue of needing a new flight plan using FL200 and accounting for a much higher fuel burn for such an abnormally low cruise altitude. Got new plan. Launched for Mexico.

 

Flying down the east coast toward MEX at FL200, passing through Atlanta Center's airspace, about 2 A.M., dark and peaceful and good weather... I felt my ears "pop" and a moment later the Flight Engineer called out calmly and clearly "Losing cabin pressure" and then his Loss of Cabin Pressurization Checklist items aloud "Cabin Pressure Controller to Manual", "Main Outflow Valve to Closed", etc.

 

We asked for an immediate descent to 10,000' and were granted it by Atlanta Center.

 

Since we were only at FL200, I elected to moderate the descent rather than do an unnecessary maximum rate emergency descent but I did ask the FO to put his mask on and gave the jet to him and I took over communicating and navigating.

 

We leveled at 10,000' and went through the checklist for regaining cabin pressure a second time, but to no avail. We were sure to be without any pressurization for the remainder of our flight.

 

Contacted Company Dispatch with the news, after a few moments they came back with the suggestion of diverting to MIA (Miami) where we had a maintenance base and asked for my approval. We checked the weather enroute and at MIA and our fuel remaining was more than adequate even for the very low cruise altitude of 10k. So we accepted the change and asked ATL Center to change our destination to MIA. A few seconds later they cleared us to ATL via present position direct MIA.

 

Now heading towards Florida, about ten minutes after getting cleared to MIA, dispatch calls and says "Change of plans, MIA base has no ACMs in stock, but there is one at our GSO (Greensboro, NC) base, so please divert to GSO instead".

 

So, we did. This time ATL asked us if we had any other problems or issues other than the loss of all pressurization and we routinely assured them we did not, that, in fact, our company was just having trouble with where they really could do the maintenance required (an ACM change out) in the shortest time.

 

Cruising towards GSO now and dispatch rings us up yet another time... This time they start with a profuse apology for so many changes and go on to explain that about 1/3 of our cargo on board ( about 80,000 lbs. of our total 250,000 ) was going through the MEX stop and on to IAH... so now, they plan to overnight the ACM unit to IAH and they want us to deliver the 80k lbs to IAH now, so could we PLEASE divert to IAH ?

 

Quickly checked weather and fuel considerations, and using Dallas as the required alternate, we just had enough kerosene to do it safely and legally.

 

Called ATL Center, apologized up front for being so much trouble, and then asked for a change in destination to IAH.

 

Crickets.  More crickets.  Finally, I called them again, "Atlanta Center, do you read ?".

 

Atlanta comes back in a slow, measured voice with "Are you experiencing other difficulties ?" plus some classified words and/or actions, and I can't say what else was said or done or I would be breaking federal laws to do so, but there were things said and done to indicate that they believed we were being hi-jacked.

 

Using classified means at our disposal, we were able to convince them otherwise and they did finally clear us to IAH and we went there without further ado.

 

One crazy night.

 

 

 

 

 

 

 

I found this in the comment section of that video.

 

"It Was going back home after a C-check in Alverca. Swapped aileron controls (so when a right input, the a/c would turn left and vice-versa). Only elevators, rudder and thrust available to control the aircraft. As far as I've heard from someone who talked to the crew when things were settled down on ground, no issues when the autopilot was connected, but as soon as they would disconnect it, the controls were lost everytime. One of the four tonneaux ended at around 4000ft on a 90º nose down attitude. Adding to these awkward conditions, the wheather here in Lisbon area have been awfull the whole day with pouring rain, heavy clouds and low ceiling, so they had no visual geographic references, plus they were unfamiliar with the terrain and there's where the F-16s came in, to guide the E190 to a safer place. After "learning" to control the plane, all calmed down a little bit, but they needed an airport with better weather/visual conditions and Beja was the best(first option was sunny Algarve's Faro), which is also in a sparsely populated (thus the lowest FR24 coverage, adding to the fact that the a/c doesn't have ADS-B and only shows up in MLAT) area so in case of a crash, the possibility of having victims on the ground was much lower. On the first landing attempt, the aircraft wasn't well aligned to the runway so a go around was performed. On the second attempt they were a bit too high and went around again, before finally successfully landing on the third attempt. Of the 6 pob, two were taken to a local hospital with minor injuries and a third person, someone from the administration of Air Astana was reporting some heart issued ans was also taken to the hospital, which all three left by the beginning of the evening."

There have been a few reversed controls incidents in our aviation history... most end in fatal accidents for obvious reasons. The folks in your above anecdote were very lucky and did a great job of airmanship.

Researchers Show Parachutes Don't Work

Twenty-three people agreed to be randomly given either a backpack or a parachute and then to jump from a biplane on Martha's Vineyard in Massachusetts or from a helicopter in Michigan.

Nobody suffered any injuries so it's true that parachutes offered no better protection for these jumpers than the backpacks.

I just discovered this series yesterday. I binge watched the first season and now I'm about to watch the first three episodes of the second season. It's a very good show.

Anyone care to explain this? Especially given his current circumstances? Think he flipped and is calling out the ones who shared his 'tastes'? Just seems a very odd thing to release right after being charged. :bajan:
