Bitchin' Betty
Many years ago (1976?) after Belenko defected in a MiG-25, there was a feature in Readers Digest about the incident. When he ran low on fuel a female voice "reminded" him. He was very surprised at that. Which surprised me a lot. (That he was not aware of the system.) (Or did it only surprise the "ghostwriter"?)
Was the B-58 the first American type with the system? (female?)
Digressing again. The (deep) stall warning of the Trident was so infernal, that it was mentioned in the "Staines" accident report as a possible contributory factor.
