The two Saints fans were spotted making airplane gestures just days after the 28-year-old's footballer's body was recovered from the downed aircraft at the bottom of the English Channel.
It was this search that resulted in Sala's body being found on 4 February, however, Ibbotson's body is yet to be discovered.
Having signed for a Cardiff record fee, Sala was travelling to Wales in a light aircraft which vanished north of Guernsey on January 21.
Although Mr Ibbotson, 59, of Crowle, Lincolnshire, has not been located, poor weather conditions meant a "difficult decision was taken to bring the overall operation to a close", a spokesman for the Air Accidents Investigation Branch said on Wednesday. "Many of us kept a glimmer of hope for you, Emiliano", football icon Maradona said on Instagram, following the identification of the body.
