We had a similar accident at our office with a MBA Revision D only a few months old. The MBA was dead but the SSD seemed undamaged. We ordered a new MBA with the same configuration and i just opened it up and exchanged the SSDs. New one with the old SSD inside booted without issues, OSX running perfectly and all data saved. I now have a spare 256 GB SSD but oh well.
Mind you this goes for the Revision D Model, so far there is no known Adapter or Interface to get the data from Revision D SSDs over USB/SATA or something like that. The SSD looks more like an old school SD RAM Block and seems to be another interface overhaul by Apple. Even the guys at the Apple Store had no possible way to interface with it except slapping it into another MBA.
Pretty stupid from Apples Side if you ask me since you are really screwed if you have no second MBA or some sort of Magician. Regular Backups are your friend. I still have hope that Delock or some other company will release some kind of Adapter to plug it into other computers.
