Ramon Morilas Holds the Max Altitude record @ 24,895ft the BG record has never been proven and was never submitted.. Still an Amazing feet!!!
The time to climb records and Max Altitude records do have Different rules, The Max altitude records can be flown from any height.. I think Ramon took off from Hushe's Valey (Pakistan) at around 14,000ft
The UK record set by Giles Fowler from the RAF team on the Bailey Matrix Hornet did 18,305ft from sea level!! Personally I think this is much harder to do and this is the way I Plan to do it too!! sea level too XX,000ft
