The flight was carrying Cardiff signing Emiliano Sala and one other person on board.
Argentine footballer Emiliano Sala was one of two people on the small passenger aircraft that disappeared from radar on Monday evening.
Guernsey Police have now said the chances of finding Sala alive are "slim" if the plane carrying the Cardiff striker over the English Channel landed on water.
The official Guernsey Police twitter account posted a series of tweets, which stated that: "During the course of the 15-hour search, which used multiple air and sea assets from the Channel Islands, UK and France, a number of floating objects have been seen in the water.
"We have been unable to confirm whether any of these are from the missing aircraft."

They then posted an update to let people know that the search had stopped, and that the plan was to resume the search at sunrise on Wednesday morning.

The Cardiff City CEO, Ken Choo, also released a statement which read:
"We were very shocked upon hearing the news that the plane had gone missing. We expected Emiliano to arrive last night into Cardiff and today was due to be his first day with the team.
"Our owner, Tan Sri Vincent Tan, and chairman, Mehmet Dalman, are all very distressed about the situation.
"We made the decision first thing this morning to call off training with the thoughts of the squad, management staff and the entire Club with Emiliano and the pilot.
"All of us at Cardiff City FC would like to thank our fans, and the entire footballing family for their support at this difficult time.
"We continue to pray for positive news
