Did you know you can try BASE with a tandem jump?
This skydiver had a double malfunction after a suspension line got caught on a tab, on the closing loop tab, causing the main to inflate and immediately go into a dive. When he cut away, his main risers disconnected but the suspension line had become too tight around the tab, leaving the main trailing behind.
You see the result in this video below (don't worry, he's okay!)
He did not have a hook knife. RSL was in use.
Sun Path issued a type of warning for these containers. This was a known issue in the early 2000s that has now been addressed. He got lucky. Late 90s Javelin owners: please make sure your gear has been made airworthy.
Jump number: 108.
Container: Sunpath Javelin J1
Main: Stiletto 135
Reserve: Microraven 150
Note, it can be worth working into your emergency procedures to make sure your main is clear with a quick visual check before pulling your reserve handle (altitude permitting).
