U fiirso qoraalka hoose ka dibna ka jawaab su'aasha kadib isla luqadda qoraalka:  Maalintiisii ugu horeysay, Armstrong waxaa loo xilsaaray inuu duuliyo diyaaradaha daba-galka inta lagu gudajiro diyaaradaha tijaabada ah ee laga soo saaray diyaaradaha wax laga beddelay. Waxa kale oo uu duulay diyaaradaha wax laga beddelay ee wax duqeeya, mid ka mid ah howlgaladaas ayaa waxaa ku dhacay shilkiisii ugu horreeyay ee duulimaad ee Edwards. Bishii Maarso 22, 1956, wuxuu saarnaa Boeing B-29 Superfortress, kaas oo ahaa inuu hawada ka tuuro Douglas D-558-2 Skyrocket. Wuxuu fadhiyay kursiga darawalka midig halka taliyaha kursiga bidix, Stan Butchart, uu duuliyay B-29.Markii ay u kaceen 30,000 feet (9 km), matoorkii lambarka afraad ayaa istaagay oo matoorku wuxuu bilaabay inuu dabaylo (si xor ah u wareego) hawada. Butchart wuxuu garaacay qalabka joojinaya wareegga, wuxuu ogaaday inuu gaabis yahay laakiin wuxuu bilaabay inuu mar kale wareego, markan xitaa ka dhaqso badan kuwa kale; haddii ay si dhakhso leh u wareegaan, way kala jabi lahayd. Diyaaradoodu waxay u baahnaayeen inay xawaare hawada ah oo ah 210 mph (338 km/h) si ay u bilaabaan xamuulkooda Skyrocket, B-29 ma soo degi karin iyadoo Skyrocket ay ku dhegtay caloosheeda. Armstrong iyo Butchart waxay diyaarada u rogeen dhanka hoose si ay xawaaraha u kordhiyaan, kadibna waxay bilaabeen Skyrocket. Markii la soo raray, mashiinkii afarta ahaa wuu dillaacay. Waxay burburisay mashiinkii 3aad waxayna ku dhacday mashiinkii 2aad. Butchart iyo Armstrong waxaa lagu qasbay inay xiraan mashiinka 3aad ee burburay, iyo sidoo kale mashiinka 1aad, sababtoo ah xawliga ay abuurtay. Waxay sameeyeen hoos u dhac gaabis ah oo wareegaya 30,000 ft (9 km) iyagoo adeegsanaya kaliya mashiinka lambarka-labaad, waxayna si nabad ah u degeen. Armstrong wuxuu u adeegay duuliye mashruuc duulimaad oo ka mid ah dagaalyahanada Century Series, oo ay ku jiraan noocyada North American F-100 Super Sabre A iyo C, McDonnell F-101 Voodoo, Lockheed F-104 Starfighter, Republic F-105 Thunderchief iyo Convair F-106 Delta Dart. Wuxuu sidoo kale duulay Douglas DC-3, Lockheed T-33 Shooting Star, North American F-86 Sabre, McDonnell Douglas F-4 Phantom II, Douglas F5D-1 Skylancer, Boeing B-29 Superfortress, Boeing B-47 Stratojet iyo Boeing KC-135 Stratotanker, wuxuuna ka mid ahaa siddeed duuliye oo xariif ah oo ku lug leh gaariga cilmi baarista ee Parasev paraglider...  Su'aal: yaa duuliyay dayuuradaha duulaanka maalinta koowaad?
