Hot air balloon flies underground - level 2
A seventy-year-old Austrian adventurer landed a hot air balloon in a cave 200 metres deep. He was the first man to fly a hot air balloon underground. The flight took about 25 minutes.
The old man’s mission comes exactly ten years after a fellow Austrian jumped down the cave with a parachute.
Difficult words: adventurer (person who enjoys adventure), fellow (somebody from the same country).
