Was just watching the news here in Holland. One flight school here in the South of the country has gone bankrupt leaving quite a few students out of pocket.
I thought I share this with you guys and I am aware this has been discussed in the past but:
You should never ever make payments of 100 000 Euro upfront

to a flight school. This has happened in the above case. Use payments in instalments instead if you decide to embark on this very risky adventure.
