"Choppergate" cost one politician her job, now it has cost a group of year 12 students their muck-up day.

Christian College in Geelong grabbed news headlines last year when students from the graduating class flew into school on a helicopter on their muck-up day.

Last year a group of students chartered a helicopter to land at a Geelong school.

The chopper prank was a homage to Bronwyn Bishop, who had hired a $5000 private helicopter to fly from Melbourne to a Liberal fund-raiser in Geelong – and had to relinquish the Speaker's chair as a result of the ensuing furore.

At the time, Christian College principal, Glen McKeeman confirmed that a "helicopter chartered by some students landed on the oval at the senior campus during celebration activities".
