Angus Houstons Bio straight from the ADF website..
Air Marshal Houston joined the Royal Australian Air Force (RAAF) as a cadet pilot in 1970 and spent the early part of his career flying Iroquois helicopters in various parts of Australia, Papua New Guinea and Indonesia. After graduation from Flying Instructors Course in 1975, Air Marshal Houston completed several instructional tours on Macchi, BAC Strikemaster and Iroquois aircraft. A posting to the Republic of Singapore Air Force (RSAF ) from 1976-1978 was followed, by two years at No 9 Squadron at RAAF Base Amberley. In late 1979 Air Marshal Houston was posted to Hill Air Force Base, Utah USA for exchange flying duties with a United States Air Force helicopter unit. In 1980 he was awarded the Air Force Cross (AFC) for an open sea rescue in gale force winds the previous year.
After a further posting to No 9 Squadron as the Executive Officer, and staff training at RAAF Staff College, Air Marshal Houston was posted to the Department of Air (Development Division) where he was involved in the Blackhawk helicopter Project. In 1987, Air Marshal Houston assumed command of No 9 Squadron to introduce the Blackhawk helicopter, to relocate the unit from Amberley to Townsville, and to transfer the capability to the Australian Army. In 1989 he enjoyed one year as a Squadron Commander with the 5th Aviation Regiment. Air Marshal Houston was admitted as a Member of the Order of Australia (AM) in 1990 for his work in the transfer of responsibility for Blackhawk operations.
Following graduation from Joint Services Staff College, Air Marshal Houston was posted to the Joint Operations staff at Headquarters Australian Defence Force and was involved in strategic planning during the Gulf crisis of 1990/91. On promotion to Group Captain in July 1992, he assumed the post of Director Air Force Policy and negotiated the establishment of the RSAF Flying School at RAAF Base Pearce. After completing a C130H conversion in 1993, Air Marshal Houston commanded No 86 Wing from 1994-95.
So we have him flying Helos for most of his career, with a C130 conversion as a Group Captain non unit pilot. (For non ADF types that would generally mean a local training area command and nothing out of the Richmond CTA without a QFI in command.)
The much vaunted "Flying in the US" would have been all below 10,000' in Iroquois. There is ZERO commercial experience in this Bio.
I have as much respect for the man as anyone else, but as previously stated, he would have been looking out for the military only on this committee, and is patently unqualified to comment on the effects of these airspace changes on large capacity RPT jets.
The largest jet he has ever flown is a Strikemaster!!!
