Project managers can report "first fix complete" or "second fix 50% done" and others can ...
Smoke candles and blower-door tests can help identify less-than-obvious leaks. The Weatherization article describes methods for energy savings further. If infiltration is reduced below 0.35 ACH, it is recommended that mechanical ventilation (typically an exhaust fan or heat recovery ventilation ) be implemented.
The transferred fuel was lost through the fractured fuel line, which was leaking at about 13 tonnes per hour (more than 3.6 kg/s). This caused a higher-than-normal fuel flow through the fuel-oil heat exchanger, which in turn led to a drop in oil temperature and a rise in oil pressure for the no. 2 engine.

A 6-foot (1.8 m) break in the pipeline resulted in one of the largest inland oil spills in U.S. history (the largest was the 1991 spill near Grand Rapids, Minnesota [1]). The pipeline carries diluted bitumen (dilbit), a heavy crude oil from Canada's Athabasca oil sands to the United States. [2] Cleanup took five years. [3]
These concerns were sufficiently great that NASA did significant work developing an emergency-use tile repair kit which the STS-1 crew could use before deorbiting. By December 1979, prototypes and early procedures were completed, most of which involved equipping the astronauts with a special in-space repair kit and a jet pack called the Manned ...
