Plane Problems

The plane will be a right off though.
obviously it will depend on the damage to the aircraft, and much as a car insurance claim, the age/hours of the aircraft will be a factor.
if this landing is nice and gentle, and the damage light, it could be back in the air within a couple of months.
It'll be the first flight of the jet operationally with the new owner. When it was built at Gulfstream it'll already have been through a production flight-test schedule to check everything worked as it should before it was delivered.
There are fail-safe systems built into the gear. The gear powers down hydraulically, and the hydraulic systems have redundancy with an emergency gear lowering system. There's a hydraulic accumulator with enough pressure to blow the gear down. (The Space Shuttle emergency system is to open the doors and let gravity do the work). The snag is the gear has interlocks to ensure the doors don't close onto the gear when it is going up or down, and if there is a problem with one of these interlocks then the gear might not operate as it should. It wouldn't be the first time an engineer has left a spanner in the wheel well which dislodges in flight and jams something.
Normally when one wheel jams halfway the crew will push and pull on the yoke to apply some 'g' to try and shake it down. Failing that some guys have 'bounced' the good mainwheel on the runway to persuade the others to drop. Gear stuck halfway is a pain; having all jammed up is usually better as you can plant it onto the runway gear-up onto a pre-laid foam blanket and normally walk away...
Doesn't happen very often. You could always take the train...
Incidentally, it'll have two pilots on board. The media always refer to 'The Pilot'. Pi$$es off all the first-officers in the right-hand seat!

...what to say when talking down the pilot ...
www.alexisparkinn.com/photogallery/Videos/flightassist.mp3 (sound file, about 9 min.)
It's the record of a mayday request of a VFR pilot lost in the clouds.
The Gulfstream crew will be experienced chaps or chappesses with Airline Transport Pilots Licences and Gulfstream type-ratings. They go into the sim regularly to practice (amongst other things) lots of different emergency drills. When they have a problem they're in charge, they don't need anyone on the ground to 'talk them down' as such. They'd have been on the radio to a Gulfstream technical representative to chat about the gear snag, but other than that they're as qualified as anyone else to land a broken jet.

Challenger 604 captain here,
We do this drill every six months in the sim, as well as every other conceivable problem. Team work with the other pilot gets the job done. I havent seen the footage as I am stuck in Budapest on a trip so any links would be appreciated. Mind you this bloody cold spell and freezing fog makes it interesting to fly in andout of the UK these days

The following is all in good humour
Aargh! I'm sorry, but that spelling is just dreadful and I couldn't help myself but post! You were looking for:
"Write-off*" not "right off"
and
"Plane" not "plain"
0/10 gentlemen!
I can see the whole, "He'll break too late!" and, "He might loose control!" coming up soon. :weep:
*You can argue about the hyphen if you wish.
