Iron Man films Informatics Part 3: Mark I armor

This one started it all: the very first model, a crude and basic suit built from hundreds of spare parts and various pieces of scrap iron. Tony Stark designed it to protect himself and escape from the cavernous prison in which he was held captive. The armor included rudimentary, though effective, equipment and weapons. Two flamethrowers on each forearm give off blasts of flame covering a distance of 25 feet. The helmet served only as a simple shield, and was not fully sealed. Stark refashioned the special iron-copper-magnesium alloy from disassembled Stark mortar cannons into the Mark I armor, rendering it especially bulletproof. To power the thruster boots, Stark reportedly siphoned the propellant fuel from four Stark S-class ballistic missiles into two Stark M-class mortars, creating two homemade fuel tanks, welded shut except for valves connecting fuel hoses that led down to the Mark I's legs. 

He had to quickly build the suit to evade detection and make the deadline for which Raza expected the Jericho Missiles to be completed. Tony managed to complete the suit and make it out alive, but he failed to save Yinsen. He killed many of the terrorists and burned their weapons. Due to its limited flying function, the thrusters shorted out and Stark crash-landed in the middle of the desert. Upon crash-landing, the suit was disassembled and Stark was forced to abandon it; he was soon rescued by James Rhodes and US armed forces. Nonetheless, this armor paved the way for future Iron Man suits. It was collected by Obadiah Stane and used as the basis for the Iron Monger armor. The pieces were eventually collected by Tony and displayed in the Hall of Armor. It was later destoryed alongside Mark II to VI from the attack of the Mandarin's helicopters.
