Ok as all the other posts are much better i have changed the size of the spider to 'Dinner Plate' size, and that it was fully venomous, veraciously hungry and pissed off.
and when i landed it ate its way out of the back of the tommie.
Speaking of 172 vents the one on the plane i got my rating in was held in by selotape, it came out an clonked me one on the head when i was doing steep turns.
No king cobra's though....
