I would decide not to scuba dive -- or climb a mountain, or parachute from an airplane -- if I felt the potential risks and costs outweighed the potential benefits. In the case of scuba diving, such risks include SCUBA apparatus failure, the Bends, nitrogen narcosis, shark attack, or being stranded in mid-sea following a group diving expedition. There would also be the cost of training, certification, and equipment (whether renting or purchasing). How I weigh these against the benefits of diving (the likelihood of adventure, potential for learning, bragging rights among my peer group, etc.) is a judgment call that only I can make for me, and only you would be able to make for yourself.
Doing It Right (DIR) is a holistic approach to scuba diving. The DIR approach (and name) evolved out of the Woodville Karst Plain Project (WKPP) in the mid-1990s.
It was not designed to open in mid-air and have nescessary precautions such as the door frame being actually bigger than the door. However, it is still possible and if accomplished, it will risk the 777 breaking up in mid-air
OF COURS NOT!it wud take that the temperature is -90c for it to freaze
No.
Hovering in mid-air is not physically possible without the help of special equipment like a jetpack or helicopter. Gravity always pulls objects towards the ground, so staying suspended in mid-air requires continual force countering gravity's pull.
the potential energy of sky diving is while you are in mid air your body is relaxed and the kinetic energy is when you have to pull the parachute to keep him up in the air before he reaches the ground
No.
Yes, it is possible for lightning to strike a person who is floating mid-air. Lightning looks for the path of least resistance to the ground, so if a person floating mid-air provides that path, they could be struck. However, the likelihood of this happening is very low.
Crisis in Mid-Air was created in 1975.
Mid Pacific Air was created in 1981.
Yes, in fact he can save lives in mid air.
