Re: [Tampapete] BASE jumping from hot air balloon!
Here's what the FAA Flight Standards say:
VOLUME 3 GENERAL TECHNICAL ADMINISTRATION
CHAPTER 12 INTRODUCTION TO 14 CFR PART 91 RELATED TASKS
Section 2 Balloons
3-333 TETHERED BALLOONS.
A. Free and Tethered Flight Considerations. If a balloon is considered an aircraft under one circumstance (such as free flight), it must still be considered an aircraft under other operating circumstances, including tethered flight. Tethered balloons are considered aircraft, and must be operated in compliance with all construction, certification, airworthiness, registration, and operating regulations applicable to aircraft.

You decide. I call it a "parachute jump," and the FAA probably calls it a "skydive"
