It *is* in fact possible to land the 747 at the Sand Shores airstrip...the trick is in learning *why* the plane blows up - there are large boulders on each side, and other small objects, that will clip the wings. You'll often hit these if you touch down at the beginning of the runway. Keep a mental note of where these objects are, and try and touch down after those objects - because of the mechanics of the game, the 747 doesn't require much stopping distance. Quick-save, and either taxi down toward the east end to try and turn around, or just throw it in reverse and back up to the boulders, to take off again. Should just barely be enough room.
Took this after I posted this reply, to see if I could do it on the first try.
I found this thread after googling to see if anyone had been able to land it at Grapeseed. I'm guessing there's no frickin' way.
And, just throwin it out there, since everyone else is serving up their $0.02: I didn't see anyone complaining about anything here (except people complaining about the alleged complainers of course). I love this game, I've played it nonstop since Sept 17th. I have not played, and probably won't play, anything else for a very long time...and I still agree with the OP. By now even the most die-hard fans of this game have some things they'd like to see in here. I can think of a few dozen. Doesn't mean I don't like the game or I'm complaining. There's just...MORE stuff I'd like to see in it. On the large scale, I'd like to see another huge city way off the coast... like the placement of Liberty City 15 or 20 miles off to the northeast, or some other large, inhabited islands to visit (and perhaps, have a reason to visit). I'd like to see the creation of new storylines, like I dunno...Tales of Los Santos. Sagas of San Andreas.
And that's what 90% of these so-called complaining posts are -- just observations from people who truly love the game, and who envision new things they'd like to see added.
I wouldn't mind a flyable "medium", as the earlier poster called it. The 747 does seem to fly slower than a real one, but response times are about right. They're respond to control inputs like I respond to my alarm clock at 6am after 2 hours sleep. But that's how the real one flies. The "medium" (whether it's a 737 or the 767, as I'm inclined to believe since the OP sounds like he knows aircraft.) would be nice if it mocked its real-life counterpart, for times when you don't wanna fly a garbage truck with wings, and the Luxor acts too much like an F-16.
To the OP, you asked why people refer to them as a 737....and I would have to say most likely, it's because it doesn't fly. No seriously, if this was a flyable model and not just static scenery, it would have undergone enough scrutiny by the public to be properly addressed. As much as I love A/C, I never gave the thing another glance once I found out it was a scenery object. As with any object in the game, if I can't fly it, drive it, throw it, kill people with it, break it or blow it up, I just don't care what it is. To me it's akin to scrutinizing the genus and species of the shrubs in Michael's front yard or identifying the geological makeup of Mt. Josiah.
