Lab tests revealed not alcohol in the pilots' blood, but a host of toxic chemicals including oil fumes, anti-freeze and even propane.
The Air Force grounded the entire stealthy F-22 fleet on May 3rd and launched an investigation.

Captain Jeff Haney exhibited the similar symptoms just before he crashed and died in Alaska in November of 2010.
