We all know that speeds in excess of 8,000 m/s are possible outside the atmosphere are possible, but how fast can you go inside the atmosphere? Objectives: Go as fast as you can inside Kearth\'s atmosphere. -Try to beat my record. -Try to beat your personal best. -Try to set the record for this challenge. Official Rules: 1: You may not exit the atmosphere during this challenge. 2: No modded parts are allowed. 3: You may only use the stock parts, Sunday Punch\'s pack, the C7 Flight Pack, and Silisko Industries Donut Research and Spacecraft Development Pack. 4: Adding screenshots is encouraged, but exceptions will be made for those working on secret projects (like me). You do not need to maintain level flight to be eligible for this challenge. *As of the 0.10.1 revision, the drag model has been heavily reworked, and the atmosphere now extends to 68,000 meters! I suggest you resubmit under these new conditions! Altitude limit still applies.* My first attempt got me 333.6 m/s with an experimental craft I call Gnat I. The second iteration of this line of rockets is Gnat II, and I\'ve reached speeds of 338.7 m/s with it. Gnat III got me 388.2 m/s. CURRENT RECORD HOLDER Salda007 at 1775.3 m/s, flying an extended-parts, level flight class aircraft! He is no longer using the C7 Micro Fuel Tank, but he beat his previous record!
