Nearly crashed my MAVIC in Sa Foradada cliff with big hole in Mallorca

A marvelous cliff with a 3m wide hole at 60 m altitude. After passing through the cliff's hole, I lost connection and the MAVIC returned home as programmed... The return mode was set to 80m...the cliff was 81m...Thanks to the automatic detecting devices that corrected the auto return flight ;-) And thanks to Nature that there was no overseing rock on the auto climb art...
