A 15-year-old boy has died after the small private plane he was flying crashed into the side of a skyscraper in Florida.
The teenager was supposed to be having a practice flight, but took off in the single engine Cessna without permission, crashing into the 28th floor of the Bank of America building.
Lesson
As the young pilot, Charles Bishop, started his usual flying lesson, his instructor told him to do a pre-flight check and walked away: but instead the boy took off.
Under-16s are not allowed to fly alone on the US, so the coastguard sent a helicopter to stop the plane.
The teenager ignored the coastguard's signals to land, but it's not yet known whether he flew into the building on purpose or couldn't avoid crashing.
Reminder
The FBI say the crash is nothing to do with terrorism, but it's a reminder of the 11 September attacks when two hijacked planes slammed into the side of the World Trade Center.
Luckily there were very few people in the building at the time and no others were hurt.
