==Notable uncrewed sub-orbital spaceflights==
* The first sub-orbital space flight was on 20 June 1944, when [[MW 18014]], a [[V-2 rocket|V-2 test rocket]], launched from [[Peenemünde]] in Germany and reached 176 kilometres altitude.<ref>Walter Dornberger, Moewig, Berlin 1984. {{ISBN|3-8118-4341-9}}.</ref>
* [[Bumper (rocket)|Bumper]] 5, a two-stage rocket launched from the [[White Sands Proving Grounds]]. On 24 February 1949 the upper stage reached an altitude of {{convert|248|mi|km}} and a speed of {{convert|7,553|ft/s|m/s Mach}}.<ref>
