Sometimes you just can’t keep an airline down, even when it’s declared bankruptcy and stopped flying. All-business Silverjet, which shut down on May 30, 2008, may be coming back to life. Like a zombie, it just can’t be killed… because it’s already dead.

The airline, which flew Newark to London (Luton) to Dubai in Boeing 767s, has received an offer in bankruptcy by a Swiss investment firm, representing private clients, possibly the Reuben brothers, themselves already big Silverjet creditors who seem intent on throwing more good money after bad.

Other recently-bankrupted airlines haven’t been quite so lucky — if a zombie’s life can be considered “lucky.” Eos Airlines is liquidating and auctioning off assets. Maxjet is being turned into a charter airline via the courts. At least L’Avion is still kickin’! (Update: L’Avion is now rebranded OpenSkies.)

But even if it does reopen for business, would you want to buy a Silverjet ticket and risk being stranded (again)? Other airlines on the New York to London route offer more frequencies — and a more established frequent flyer programs, for that matter. (Except to Stansted. Perhaps unsurprisingly, American Airlines just recently canceled its New York to London-Stansted route, which it launched purely out of spite for Maxjet and Eos.) Virgin Atlantic has actively been trying to recruit Silverjet customers. Would those travelers really defect again? I sure wouldn’t.
