Every twin engined plane I've flown on has been average. A330, 777 even the 787 were all average, nothing special. But when I flew on the A380, I was probably the most comfortable I've ever been on a long haul flight. The A380 is quiet, spacious and comfortable. So far, no other plane has come close.

So cute! And a 16 month gestation? That’s a long time to wait.
It is a shame about the A380’s, though. They were supposed to be the next big thing and now airlines are trying their best to get rid of them. They’re scrapping planes that are only 10 years old. I think Boeing has their 777x ideally placed. As A380’s and 747’s are removed from service, there will still be a need for high capacity long distance routes. The 777x might just be the jumbo jet of the future. However, nothing can beat the scale and grandeur of a four engined jet.
I’ve been working on a 747 at Cincinnati airport all this week. There’s no comparison between it and a 767. And it was all going well on the 747 until we were changing this hydraulic valve in the wheel well and hydraulic fluid dripped onto the apu bleed duct, which was 400 degrees. That hydraulic fluid, Skydrol, boiled off. It created this pungent, choking cloud. We all got out of that wheel well pretty quickly. It felt like my throat was on fire. And I was coughing for quite a while afterward. That Skydrol was bad enough as a liquid. But a gas? It’s pure hell. It’s practically a biochemical weapon. I wouldn’t wish breathing in that stuff on my worst enemy. We shut the apu down and waited for the duct to cool off before continuing. We changed out the valve, but a ton of Skydrol leaked out. We had to get buckets and mats to clean it up. It looked like the 747 we taking a piss from it all. There’s no doubt the hydraulics had to be refilled after that.

Yeah, the A380 is of course the largest passenger aircraft in the world so they must have a lengthy gestation to match.
How awesome that you were working on a 747! Must be a real thrilling experience to get so up close and personal with the aircraft. As for the Skydrol leak went, I heard the stuff is pretty toxic on its own and boiled off. I wonder how the 747 fared with 'taking a leak' lol

It is thrilling. I enjoyed it. But since it’s larger and more complicated, there’s a lot more that could be wrong with it. That gaseous Skydrol was pure hell. I’d take working with it in liquid form any day than have to breathe it in again. The liquid smells bad and is very slippery. But at least you can combat that, not if it boils off. As for the 747 leaking Skydrol, it was pissing out all over the place. Multiple gallons of it. Me and another mechanic were running through the hangar to grab buckets and pig mat to absorb it and gather it up. I mean, this stuff just kept coming. They were throwing out multiple soaked sheets of pig mat from the wheel well. We had garbage bags and cans to wheel it out of there, though. I’d rather work with fuel. If you have to enter the tanks, they make sure it’s drained and the tank sumps are dry, then the vapors are vented out. So it’s completely dry and there’s no risk of getting soaked. But that would mean crawling into a fuel tank, which is probably easier on a 747 than a 767.
