His three books:

"A trace in the Sky"
" Mit dem Wind um die Welt" (D - Piper Verlag) vergriffen
" Spuren am Himmel " (Malik Verlag)

have contributed to Bertrand Piccard becoming known as a "Scientist-adventurer", one who endeavours to combine the scientific background inherited from his family with his desire to explore the great adventure of human life.
"In the most intense moments of my experiences, part of my mind often prepareswhat I will later recount. Out of this comes the need to record in writing the fleeting impressions that I wanted to last forever. My books have no other purpose than to give readers the desire to go beyond their limits, not on the Earth on the seas or in the air, but within themselves."
