So what you're saying is that the Viking Kitties are now airborne?
Cheers!
Correct! The kitty micro-helicopter you posted, if GPS-guided rather than merely radio-controlled, could be positioned in the runway path of a turbofan...which is a very delicate thing.
No on-board explosives are needed. Small birds have brought down airliners. Cartoons were published of terrorists training flocks of birds after Captain Sully Sullivan’s plane was brought down, so the idea of terrorists, like Hamas, reverse-engineering airline bird-strike crashes is out there.
