[The] fuselage panels were manufactured to fit only loosely on the ground. Proper alignment was achieved only when the airframe heated up and expanded several inches. Because of this, and the lack of a fuel sealing system that could handle the thermal expansion of the airframe at extreme temperatures, the aircraft would leak JP-7 jet fuel on the runway. At the beginning of each mission, the aircraft would make a short sprint after takeoff to warm up the airframe, then refuel before heading off to its destination.

Meanwhile, if you'd like to know more about this marvel of engineering from the 60's:
[Vipande vya mwili] vilitengenezwa ili viweze kufanana kwa urahisi tu kwenye ardhi. Msimamo sahihi ulifikiwa tu wakati kiunzi cha ndege kilipopashwa joto na kupanuka kwa inchi kadhaa. Kwa sababu hii, na ukosefu wa mfumo wa kufungia mafuta ambayo inaweza kushughulikia upanuzi wa joto wa fuselage katika joto kali, ndege ingekuwa kuvuja JP-7 jet mafuta juu ya runway. Mwanzoni mwa kila safari, ndege hiyo ilifanya mbio fupi baada ya kuruka ili kupasha joto, kisha ikaboresha mafuta kabla ya kusafiri kwenda mahali ilipokuwa ikielekea. Unaweza kupata maonyesho yangu hapa na video inapaswa kuwa online hivi karibuni sana! Kwa hivyo, ikiwa unataka kujua zaidi juu ya hii, tafadhali chagua hii ya uhandisi ya miaka ya 60:
