Aerial refueling craft was eventually modified by Airspeed to Cobham's specification, for a non-stop flight from London to India, using in-flight refueling to extend the plane's flight duration. Meanwhile, in 1929, a group of U.S. Army Air Corps fliers, led by then Major Carl Spaatz, set an endurance record of over 150 hours with the "Question Mark" over Los Angeles. Between June 11 and July 4, 1930, the brothers John, Kenneth, Albert, and Walter Hunter set a new record of 553 hours 40 minutes over Chicago using two Stinson SM-1 Detroiters as refueler and receiver. Aerial refueling remained a very dangerous process
Non-stop decay stop codons. Stop codons are signals in messenger RNA that signal for synthesis of proteins to end. Aberrant transcripts are identified during translation when the ribosome translates into the poly A tail at the 3' end of mRNA. A non-stop transcript can occur when point mutations damage the normal stop codon. Moreover, some transcriptions are more likely to preserve low scale of gene expression in a particular state. The non-stop decay pathway discharges the ribosomes that have stalled at the 3' end of mRNA and directs the mRNA to the exosome complex in eukaryotes or RNase R in bacteria, where
