Hotel bills are paid for by the airshow/display organisers
Not entirely true - both RAFAT and BBMF have their own UINs for which hotel bills and crew subsistence are claimed against.
Units supporting Tucano, Typhoon and Tutor display teams also have to cough up for most of the expenses accrued by their crews and support personnel.
Yes, some of the costs for RAFAT are met by industry, but not all.
Apart from the minimal cost of BBMF perhaps we should pull all our display aircraft and really let joe public and the airshow circuit know how bad it is.
