Yamaha can you explain why? VLF and computers run around similar frequencies.
Say again? VLF is less that 30 kHz. Computer chips are well into the MHz range.

Plus shielding against low frequency interference is simple. It's higher frequencies that can be challenging.

For the CNN chap, no real chance of this being laptop/cell phone interference. The danger from digital devices used by passengers is interference with analog navigation signals (eg 25-33 MHz processor generating harmonics in the 100 to 133 MHz realm where the VOR/ILS signals live). It is much less likely to interfere with a digital computer - they have to tolerate much self-generated noise as it is.
