Why the pigeon-guided bomb lost its place

Was the pigeon-guided bomb abandoned because operators did not trust it?

Emerging radio and radar guidance offered alternatives, while maintaining a trained-pigeon supply was judged likely to be more expensive than conventional guidance equipment.

Radio- and radar-guided weapons were becoming available as pigeon guidance approached possible operational use. They offered an alternative to the continuing effort of training birds. A pigeon could not be electronically jammed, which gives the biological system one advantage. Maintaining a supply of trained pigeons was nevertheless judged likely to cost more than conventional guidance equipment.
