This is a fascinating claim (and video), but I can't find a ton of corroborating evidence for it: searches for "digital camera cosmic rays" bring up (1) considerations for cameras in space (much higher background radiation levels than a commercial flight), and (2) consumer photography forums where people are discussing that 2011 talk. Some of the latter seem to think that Kodak has/had a vested interest in spreading fear around digital photography, since their analog division was imploding at the time.

Any ray that might damage a ccd would also impact film stock, exposing sections into bright dots. Did kodak also not ship film by air?

Not really, no. It might be too brief to cause a chemical reaction, but powerful enough to induce a very high voltage.
