Similar story where I learnt to fly helicopters in the US:
As the story was told to me, the student progressed to a solo stage and then on or shortly after his first solo, flew into the grounds of a prison to pick up a mate.
I gather that a number of others (likely unaware of an R22s limitations) tried to pile on board and caused some damage in doing so!
The "pilot" managed to get over the prison walls, but not much further. All occupants (not sure how many at this stage) were apprehended shortly thereafter outside the prison and now comfortably reside on the inside!
