Dude i was just THERE! Flew to Kona to investigate a fire (for two days) and had a late flight out so went to the beach there, did see people snorkeling but did not have room to pack mask and fins. Very cool and chill island, love to go back for fun someday. That park area and beach are very...

One note of caution: while comm towers present readily identifiable and visible nav aids and landmarks, and will have open area around their base, they are also potential sources of high power RF that can momentarily disrupt or blind consumer grade UAV's. VERY HIGH power transmissions eveon on...

YOU ARE MISSING THE POINT: THIS IS A NEAR MISS REPORTING SYSTEM that is intended to HELP other pilots by learning from the mistakes made by others, so that YOU don't make the same mistake. The process is anonymized and safe for the person submitting their report, which is a foundational part of...

Rule of Thirds: 1/3 outbound, 1/3 return, 1/3 for emergencies.., Pushing it to the limit has its drawbacks.

EXCELLENT use of technology for maintaining heightened situational awareness, and ensuring GOOD dives!

NASA has an excellent program for commercial aviation called ASRS (Aviation Safety Reporting System) that also publishes reports of accidents and near misses as a training/learning tool. They are expanding this to include the UAS community, including hobby, part107, public safety, and part135...

excellent article and worth taking the time to read it.

LI chemistry batteries of this type are known to fail catastrophically and deflagrate during a thermal runaway event releasing large amounts of gasses and thermal energy (the speed of the reaction is just shy of qualifying as an actual explosion). When the batteries are confined (as in being...

This is NOT intended for system users (as in the users of this site who actually fly) but for regulators, solicitors, (attorneys who work for municipalities) and legal staff working for local and state government. This is all about the feds trying to head off conflicts before they are written...

Just to be clear: 1. Police only ENFORCE laws NOT create them. LEGISLATIVE acts create laws, codes, and ordinances at all levels. 2. NYC is a complex environment to police/protect and ensure any measure of public safety for a lot of reasons. 3. This is an ongoing and evolving process to...

the cinder block is a nice idea especially for the prismatic (pouch type) batteries that will not contain any failures. just remember that IF they fail that the emitted gasses vent with sufficient force to propel them around whatever room they are in if not fully contained. I investigated a...

nice choice of monochromatic for this image, and really nice perspective lines

ANY DAMAGED BATTERY IS UNSAFE!! DO NOT CHARGE OR USE IT...

Just back from a day long seminar on LI battery system fire and explosion hazards that took place in Washington DC Thursday 3.30 (presenters included UL Fire Safety Research Institute, FDNY, DOE, NTSB, and others). Deformation (swelling) of a battery case is the first symptom of impending...

while its nice everyone is weighing in on what to do, the REAL/CORRECT answer is to reach out to the TX department of Public Safety Region VII at the Capital complex and get a definitive answer. They are the authority having jurisdiction (AHJ) and enforce the rules there. ANY government...
