Tom Shephard and other Brits all claim that the FIRST thing you do when you are stuck is to stop and brew tea. This to give you some time to calmly think about it.
In a prior life I taught scientific diving for 25 years and first rule in a stressed situation was to stop, breath, think, breath....breathing was as critical as stopping since under stress we tend to hold our breath...topside or underwater that leads to hypoxia which further leads to bad judgments...it of course posses other dangers to a diver...
Collective wisdom on this forum always amazes me and I learn a lot..... even in such a straight forward topic as how to best jack up my Tunda/Hawk...might even go the empirical route and deflate a tire [big shop compressor] and confirm that the bottle jack I just ordered will fit under a lifting point....old saw: "Prior preparation prevents piss poor performance" still is valid approach.
Thanks again to all for the tidbits!
