I will be attempting to break a world record in longest indoor freefall, which will be performed by flying in a vertical wind tunnel in Prague, Czech Republic.
WHEN & WHERE
The record attempt event is set for 10th December 2013, starting at 05:00 (AM) CET (UTC+1) and planned to last slightly over 6 hours. The attempt will take place at Skydive arena, Tupolevova 736, Praha 9 - Letňany.
The event will be supported by these sponsors:
Skydive arena, a vertical wind tunnel based in Prague - CZ
AVG Technologies, producer of world renowned security software.
Keep Falling, producer of clothing and accessories for skydivers. Styrotrade, manufacturer of Polystyrene products.
I was flying in the tunnel already many times, and never thought about something as crazy as breaking a world record. Then, once, someone simply asked me "How long can one sustain flying in the tunnel ?", which sparked an idea ...
The known world records of this type were exceeded in each of the next attempts by 31 minutes (+32%), 55 minutes (+43%) and 60 minutes (+33%). My current attempt is targeting to exceed the last record at least by 63 minutes (+26%) with potentially exceeding it by 123 minutes (51%), so my ultimate target is to beat 6 hours flight time.
I have already registered the attempt to break existing world record at Guinness World Records, and received full guidelines setting rules for the event and its documentation. The current world record is 4 hours, 2 minutes and 12 seconds.

This is the current World Record.
The record attempt in Longest Indoor Skydive means to face a lot of technical difficulties, such as guaranteeing consecutive time in the tunnel and associated cost of the event, plus technical-physiological difficulties (tiredness, nutrition, hydration, urination).
Indoor freefall is a physically demanding exercise, which requires the body to burn approx. 862 kJ per hour. That means energy depletion of 4300 to 5200 kJ, which is comparable to 75 minutes of run at a good pace. Coupled with that comes excessive vibration, excessive noise, muscle cramps of whole body, etc.
ABOUT TUNNEL FLYING
Vertical wind tunnels enable human beings to experience the sensation of flight without planes or parachutes, through the force of wind being generated vertically. Air moves upwards at approximately 195 km/h (120 mph or 55 m/s which is comparable to windspeeds in hurricanes of category 3-4), the terminal velocity of a falling human body belly-downwards, although this can vary from person to person. A vertical wind tunnel is frequently called 'indoor skydiving' due to the popularity of vertical wind tunnels among skydivers, who report that the sensation is extremely similar to skydiving. The human body 'floats' in midair in a vertical wind tunnel, replicating the physics of 'body flight' experienced during freefall.
This is how the tunnel flying in Skydive arena looks like:
