smudge,
not what you need a source of heat near the lox vent. Did a few Lox runs to Patrick and Homestead from Belize. On one, with a full 500 Lox container we had a fire under the flight deck. One of the TRU's if memory serves. Quickly put out and the Smoke and Fumes Drill carried out complete with para doors open. This caused some disquiet to the (strapped in ) movers on the a/c. Normally carriage of anyone but the basic crew plus G/E and Lox escort was verboten.
But Belize Lox runs were granted an exception so some of the movers could go to Florida and buy fruit and veg etc.
Originally Lox was only cleared in the large 500 containers for carriage in the Herc when rigged for airdrop. This was so we could safely jettison it in an emergency.
When the SSP platform it was normally carried on became obsolete Lox was then cleared for carriage on normal pallets. Getting rid of one in this configuration would have been 'interesting'.
