Date: September 11, 1922
Location: Barmouth, Wales
John Morris, steersman of the local lifeboat, and another witness saw what they thought was an aircraft falling, with extraordinary slowness, into the Irish Sea. They took a motorboat out to investigate but found nothing. There was no report immediately afterwards of any terrestrial aircraft having gone missing.
If there were de-bunkers around in the day then they would have surely classed this as a Chinese lantern or maybe because of the location and circumstances, an ‘Irish lantern’, being essentially the same thing just a bit slower. Joking apart this may be one of the earliest observations in Britain of USOs in the Irish Sea.
