From the AOPA article --
"Based on conversations later with government officials, both men believe the
helicopter's radios did not work — or at least did not work on civilian
frequencies — when it first approached the 150. Martin said he was told that
during the ordeal, the helicopter landed, fixed the radio, and then returned to
re-intercept the airplane. Sheaffer said he was told twice by a DHS official
that the helicopter had radio problems and had to land. Again, DHS chose not to
comment on any problems with the radios."
