Turnaround time for passenger machines seems to average something like 5-10 minutes. The one in the background is on the runway, about to take off.
Flying (into and back) out of Lukla airport, with its 12 degree sloped and 460 m long runway, is quite entertaining. (The seeming chaos introduced by the airlines' check-in systems is almost worth a separate blog entry, but on the other hand is nothing that can't be dealt with...) Due to our issues with getting a flight out to Lukla from Kathmandu in the first place, we had decided to actually make reservations for a return flight on a specific date, rather than getting an "open return" ticket that allows more flexibility. This proved to be a smart move a month later when we were ready to return to Kathmandu, since bad weather and the going bankrupt of another airline left many people stranded in Lukla, waiting for seats on full flights to open up.
Only Jason had been at these altitudes for a prolonged time before, so we had an interesting time figuring out how the rest of us would adjust to it. General recommendations for people who don't know how well they acclimatize seem to include to move up about 300 to 500 meters a day, and to spend a rest day every 1000 m or so. So we learned all about the symptoms of altitude sickness (AMS, HACE, HAPE), but our constant self-diagnosis attempts got interfered with by various colds and other aches that everybody in our group was fighting on the way up -- not the ideal condition for quick acclimatization, it turns out.
We spent extra rest days at Namche Bazaar, where a German bakery serves really excellent cappuccino and pastries, and in Machermo, where you can attend a free talk about altitude sickness every afternoon at IPPG's volunteer-staffed Porter Shelter and Rescue Post. And we decided to head straight for Gokyo and the Ngozumpa Glacier, instead of paying Gorak Shep and the Khumbu Glacier (at even higher elevation) a visit first.
I think I personally dealt with the altitude OK. I rarely felt sick, other than having a mild cold at some time and a stuffy nose most of the time -- things I usually incur quickly when in colder climates. But after two weeks in Gokyo, climbing up the lateral moraine to get out of the glacier was still quite a strenuous task, as was climbing more than just a few stair steps. But maybe that is just they way it is. ;-)
Apart from the elevation, traveling on the established tourist routes in the Khumbu is straightforward and convenient. Overnight, you stay in lodges that provide basic accommodation for a nominal fee and make their money by selling you (generally quite tasty) meals and tea, and often Internet access or the service of charging your batteries for many rupees. During the day, you hike along established trails that you share with tourists (a lot of them -- especially during our first weeks, beginning of November), horses, yaks (in the higher regions), and porters -- often chatting on their cell phone -- that either carry supplies to the towns at higher elevation, or tourists' luggage. Rare is the Nepali who isn't friendly, helpful, and hospitable.
We ourselves had pre-arranged to hire three porters on our way up to ease our own loads and drag our caving gear up the mountains. Unfortunately but not too surprising, they did not show up as agreed when our stuff needed to go back down two weeks later, and we had to improvise with lodge-arranged horses and porters that weren't quite as reliable as we had hoped. But it all worked out in the end.
One of the most valuable gadgets I dragged up into the Khumbu turned out to be my Kindle e-reader. I read about half a dozen books on rest days, in the evening, and whenever we weren't out and about. Probably more than I've read in the past year or so. Having to carry that much paper weight around would have been a burden. The solar panel worked out nicely, too, allowing us to re-charge batteries for our Sten lights, as well as Kindles, etc.
It remains a word to be said about the organized tour groups up in the Khumbu, based on many observations during the past weeks. "10-day trek to Everest Base Camp!", etc. -- I wouldn't do it. If you want to go "trekking" in the Everest region, either go by yourself (although I would always travel with at least two persons in case something happens), or get your own porters and/or guide. This gives you the flexibility to adjust your schedule and destinations on a daily basis, rather than being subjected to a pre-planned schedule without much respect to individuals feeling sick, tired, or needing an extra day to adjust to the altitude...
