It's a long thread abt 1984,Aug 2, Chennai Airport bomb blast killed 33, injured 38. I promise you, It is very interesting. In 1983, saw start of Sri Lankan civil war.
1. Tamil Eelam Army(TEA) Kathiresan & allies wants to put a bomb in the luggage of Air Lanka flight UL-122 1/n

2. Flight UL-122, depart from Chennai Airport at 8.15PM. Bomb was timed at 11 PM, so luggage will be in cargo complex of Colombo Airport, blast is intended to damage Air Lanka properties
3. Two Luggage of accused was tagged in Chennai to reach London & Paris through Colombo 2/n

4. Those days, Indian customs only checks 5% of all luggage's. So accused thought, it will get through the plane without any problem. But due to its weight, the luggage was held by custom officials for checking, As per rules, they check the luggage only in front of the owner. 3/n

Yesterday 4 people died due to Lightning in #Virudhunagar. Every year, >5000 die in India.
This thread is about Lightning precaution & busting myth.
Many think, people die due to direct lightning strike, but most of the death happens due to the concept called step potential 1/10

If a lighting strike ~50ft distance from you. Lightning create potential gradient around its strike point. Voltage will be peak at the strike point and it will start reduce from that point. The electric current will start flowing under the earth. 2/n

If you stand above the ground keeping your two legs apart, it is equal to applying voltage between your two leg. The potential between your legs will make current flow through your body (e.g. current flow from ground to your left leg, hip, right leg then back to the ground), 3/10
