Sharks on a Plane

Very soon, in a place horrifyingly nearby, a plane is going to take off. There is no way to stop it now. The people are perfectly peaceful save for a few children whining and screeching. Sitting in business class, a marine biologist studying Caulerpa Taxifolia and sharks, sits reading Science. A pleased smile on her face is representative of  her successful weekend of research. Smugly she dreams of a possible Nobel Prize and of research grants. Little does she know what is to come.

On her left finger is half a dozen cells of the Caulera Taxifolia/ great white hybrid. The cells wash into the sink when she uses the bathroom, and they stick to the wall. If only she pays a courtesy to the next user and wipes off the basin nothing will happen. But she doesn't. BMBMBAHHHHH!
With the presence of water the cells divide sporadically, growing into an enormous shark. It breaks free from the enclosed space and runs wild in the plane.
The passengers freak out. There are screams calling for "Get these devilishly handsome sharks off this devilishly handsome plane!" The shark seems to enjoy it.

 

He couldn't ride the plane forever through. He went to say hi to the pilot, but the pilot and copilot fainted and the shark accidentally turned off autopilot. The plane was going down.

The people opened the emergency door when they got low enough and threw the shark out. The hybrid went through the router and burst into tons of individual cellular blobs, all which would grow into new sharks. The people were safe for now, but those individual cell blobs began to grow, rising into the clouds. They wait in the clouds, ready for the next time there will be... SHARKS ON A PLANE!!!!!!!!!!!!
