On landing, Aldrin and Armstrong believed they had 40 seconds of fuel left, including the 20 seconds' worth which had to be saved in the event of an abort. During training, Armstrong had, on several occasions, landed the LLTV with fewer than 15 seconds of fuel; he was also confident the LM could survive a fall of up to . Post-mission analysis showed that at touchdown there were 45 to 50 seconds of propellant burn time left. The landing on
