In the TWA 800 accident, an aircraft wake turbulence encounter did cause the breakup of the aircraft, prior to the fuel tank explosion! The NTSB attempted to cover up the true cause of the accident by removing essential evidence from the FDR Chart.
Spot the conspiracy freak .....

I seriously doubt that a 747 would come apart from a bit of wake turbulence. Having flown them for nearly 3,000 hours through a lot of different conditions I know that they can handle severe turbulence for many hours at a time without any problem at all.
