...bad judgement. This appears to be from the Tampa/St. Pete metro area (FAA Class B airspace). At the top of the ascent (about 4300 feet AGL), the vehicle rotates to what appears to the north and you can plainly see Whitted Airfield (Class D airspace). I'm having a bit of a time discerning which airspace he is in, with no telemetry, but using visual markers (as all good VFR private pilots do), this guy broke pretty much every FAA rule regarding Class B and Class D airspace (class D is restricted 0 to 2500 feet AGL). The Class B ring he was operating in if not in the Class D either had a floor of 3000 feet AGL (broken) or 1200 feet AGL (once again, broken). Now, I know I'm going to get a reputation around here of being a killjoy, but this isn't any different than what the gentleman from Alabama had happen to him. If someone picks this video out and decides to send it to the FAA, this is going to be all over the news. We really do not need this and should be actively discouraging doing things such as this. It's also not far from Madill AFB. That's a whole other can of worms that we don't want opened. EDIT: I also note that in the author's description, he says he discourages altitude tests. That's fine and dandy, but doesn't change the fact that it was done. OK, my 'get off my lawn rant' is over for the day. Second edit: decided some of my wording was a bit harsh, so toned it a little. Sorry, I don't want to see this hobby regulated into illegality. Third edit: removed the youtube embed, as the owner removed the video. Probably a smart move. And doing some further looking last night, the person evidently has an account here. I'll stop at that and assume he saw this post. While that''s a good thing, it doesn't remove the fact that it was done.
