In Bob Ward’s point-missing riposte to George Monbiot’s criticism of the Science Museum’s acceptance of sponsorship from Shell, the words “Shell” and “sponsor” are notable by their absence (Letters, 22 April). He doesn’t say if, as an adviser to the carbon capture exhibition, he thought Shell’s sponsorship was wrong, a disagreeable necessity, or just lovely. Could someone ask him?

• A Nasa representative described Ingenuity’s flight on Mars as a Wright brothers moment (Report, 19 April). More accurately, it was a Sir George Cayley moment, as he is the father of aeronautics. In 1909, Wilbur Wright said of him: “About 100 years ago an Englishman, Sir George Cayley, carried the science of flying to a point which it had never reached before.”

• It was your Other Lives page that reunited me with a long-lost university friend (Letters, 18 April). She recognised my mother’s name and photograph, as she had stayed with her several times while studying in nearby France. You were kind enough to forward the email she sent to you, and we have since reconnected, after a gap of nearly 40 years. A happy outcome.

• We “retrieve” the Guardian from the dog after she has extracted it from the letterbox (Letters, 22 April).
