In Georgia, a 3,000 lb Chevy Impala slipped off a jack and onto a young man. Without any assistance, his mother, Angela Cavallo, picked up the car and held it for five minutes until neighbors could pull her son to safety.

 As the helicopter came in for a soft landing, it suddenly careened out of control and slammed to the ground, this was all caught on film. One of the pilots was trapped under the helicopter in the shallow water. Warren “Tiny” Everal ran over and lifted the helicopter off the pilot. The chopper was a Hughes 500D, which weighs 1550 lb when empty, the pilot recovered.

The 4,000 lb BMW slipped off the jack and landed on the mechanics chest, crushing him. With no time to waste the mechanic’s 22-year-old daughter lifted the car and moved it off her father, the performed CPR to keep him breathing.

Science says that under acute stress, the body’s sympathetic nervous system prepares the body for sustained, vigorous action. The adrenal gland dumps cortisol and adrenaline into the blood stream. Blood pressure surges and the heart races, delivering oxygen and energy to the muscles. It’s the biological equivalent of opening the throttle of an engine.

Does this science explanation explain how someone who isn’t Captain America can lift a helicopter? Does science explain how these people had the strength to lift a car off of someone? Maybe science has the answer, maybe just maybe there is another one… THEM.
