Is it fair to blame HMS Penelope for the 1968 loss of an Aer Lingus passenger aircraft?
Short answerNo; the ship lacked the relevant missile capability and was far beyond plausible gun range.
NotesThe proposed explanation fails on basic capability and geography. Penelope had no surface-to-air missile system, was roughly 150 miles from the crash, and could not make a 4.5-inch gun perform the feat alleged. Those independent checks collapse the accusation before a more elaborate conspiracy is needed. Technical limits provide a direct test for sensational naval claims.
