RAF lifts ‘60-year ban' on popular treat after tests find it won't explode in cockpit
Tunnock's tea cakes have been cleared to be taken on board RAF planes after a 60-year-old myth they explode was debunked.
The snack was said to be banned from RAF flights in 1965 after one exploded over the cockpit when a captain pulled an emergency depressurising switch on a training sortie.
But an RAF Centre of Aerospace Medicine test has now found the Scottish marshmallow and biscuit base snack does not explode, the BBC reports.
The snack was put inside an altitude chamber and lifted to 8,000ft, before being rapidly decompressed to 25,000ft to see if they would explode.
Although the marshmallow escaped the tea cake's milk chocolate casing, it did 'not appear to explode and cause a risk to in-flight safety", according to the broadcaster.
Dr Oliver Bird, an instructor at the RAF Centre of Aerospace Medicine, told the BBC: 'The best advice is that the snacks are kept frozen and in their foil wrappings until pilots are ready to consume them.'
Tunnock's is a family company led by 92-year-old Sir Boyd Tunnock, whose grandfather Thomas Tunnock founded the business in 1890 as a bakery in Uddingston, Lanarkshire.
The iconic tea cake was developed in 1956. The company now employs more than 600 people and exports products to over 30 countries.

Results Day: Pass rates rise for Scottish students
The number of students who have passed their exams has risen in 2025, the SQA has said. On Tuesday, more than 130,000 students will receive their results after sitting exams for National 5, Higher and Advanced Higher qualifications. Across the three qualifications, pass rates are up on the previous year, with pupils attaining A, B or C grades. The Scottish Qualifications Authority (SQA) said 78.4% of National 5 students passed, up from 77.2% in 2024. Meanwhile 75.9% of Higher students achieved an A, B, or C grade, compared to 74.9% last year. iStock Youngsters across the country have received their exam results. Advanced Higher students achieved a 76.7% pass rate in 2025, up from 75.3% in 2024. The SQA said 2025 was a 'landmark year' of achievement and success. 'Scotland's learners should be rightly proud today – and we are proud of them,' Donna Stewart, Scotland's chief examining officer, said. 'Their hard work and commitment has made 2025 a landmark year. The rise in overall attainment at all three National Qualification levels will rightly be welcomed in classrooms and staffrooms across Scotland. Higher entries have also risen beyond 200,000 for the first time since Curriculum for Excellence was introduced.' SQA Donna Stewart from the SQA with Practical Cookery pupils at Portobello High School Meanwhile the number of vocational and technical qualifications surged past 100,000 for the first time ever. There were 110,390 students – a 22.6% increase – taking skills-based qualification awards in 2025. The awards included a wide range of areas, including leadership, employability, and personal finance, as well as a range of skills for work courses, awards, national certificates, and national progression awards. The SQA, which will be replaced by Qualifications Scotland in December, also reported that the poverty-related attainment gap narrowed at all levels of national qualifications. 'We welcome that progress towards the shared national mission to reduce inequality,' Ms Stewart said. 'All of those achievements are to be celebrated – and they belong to Scotland's learners.' On behalf of the SQA, Ms Stewart thanked all of the teachers across Scotland for the work they do everyday and who make 'Results Day possible'. 'Today is the last Results Day for SQA, after three decades of service to Scotland,' Ms Stewart said. 'We are already working hard to ensure that Qualifications Scotland builds upon the best of SQA while delivering positive change that will be felt long before Results Day 2026.'

Record number of young Scots headed to university after SQA results
Statistics released by university and college admission body Ucas show 17,350 17 and 18-year-olds will be admitted this year, compared to 16,650 last year. The number of those from the most deprived backgrounds is also at its highest, at 2060. However, the gap in the proportion of those accepted from the most deprived areas compared with the most affluent remains pronounced, with 16% from the 20% of areas described as the most deprived being accepted compared to 43.6%. READ MORE: Which MPs have received the most donations and from whom? See the full list The total number of applicants from Scotland who secured a place at university this year actually fell compared to the figure for 2024, from 31,970 to 31,850, as a result of a decline in mature student applications. Some 3660 students are set to come from abroad – an increase from 3480 from last year. Dr Jo Saxton, chief executive of Ucas, said: 'I'm delighted to see record numbers of young people in Scotland accept a place at university or college via Ucas this year. 'Today's figures also show record numbers of accepted students aged 17 and 18 from the most disadvantaged backgrounds. 'This is testament to the tremendous efforts being made to support widening access to higher education in Scotland. 'Everyone at Ucas offers congratulations to those celebrating today and I would encourage any students considering higher education, even those who have yet to apply, to explore clearing. 'There are plenty of options for you to consider, with around 27,000 courses, including more than 2,700 at Scottish institutions. 'Ucas's team of expert advisers are also on hand to answer any questions on the phone, on our website and on social media.'

An East Lothian school may have found a novel new way of closing the education attainment gap - learning the pipes and drums. A study of pupils from Preston Lodge High tracked young people who play in the school's piping programme for ten years. The research found teenagers who learned a traditional Scottish instrument outperformed their classmates in exams. Advertisement Hide Ad Advertisement Hide Ad The Preston Lodge High pipe band in action. | Preston Lodge High Pupil players were more likely to earn Highers and Advanced Highers and go on to university than their non-musical peers. The effect was not only prevalent for young people from middle-class homes, but included those from more disadvantaged backgrounds. The piping scheme at the Prestonpans secondary is supported by the Scottish Schools Pipes and Drums Trust (SSPDT). 'One of the most encouraging things to come out of this study is the fact that even youngsters from the most disadvantaged backgrounds are flying high too,' SSPDT chief executive Lindsay MacKenzie said. Advertisement Hide Ad Advertisement Hide Ad 'It is proving beyond doubt that pipe bands at school can really help bridge the attainment gap at a time when national statistics show the gap to be widening.' Preston Lodge High has had a turbulent few years with the challenges of dealing with significant disruption due to building problems. The school was found to have been built with the lightweight concrete, reinforced autoclaved aerated concrete (RAAC) - a material that can easily crack and crumble. Education Scotland assesses schools on four quality indicators. The school's most recent inspection report, from January, showed Preston Lodge received two 'weak' ratings from watchdogs and two 'satisfactory'. Advertisement Hide Ad Advertisement Hide Ad Yet the young people in the school band have far exceeded the national average in exam attainment. All 78 pipe band members between 2014 and last year were tracked from final exams through to higher education and employment and all of them have had better outcomes than their peers. A pupil from the Preston Lodge High piping programme performs. | Preston Lodge High Some 52 per cent of pipe band members attained five or more Highers, compared to 39 per cent nationally and 27 per cent overall at Preston Lodge. A total of 41 per cent left school with one or more Advanced Highers, compared with the national average of 18.7 per cent. For pupils from the two most deprived social groups, the impact was significant. Research shows 45 per cent achieved three or more Highers, compared to 38.2 per cent nationally and 40 per cent attained one or more Advanced Highers, compared to just 10.5 per cent nationally. Head teacher Gavin Clark said the impact of the school's three pipe bands was 'impossible' to over-estimate. Advertisement Hide Ad Advertisement Hide Ad 'Our pipe band has grown significantly over the past two decades from a tentative group of new players in 2007, into the flourishing figurehead of our school and its community it is today,' Mr Clark said. 'While we've always known that our young people of all ages and abilities, across the primary and secondary sector, have benefited immeasurably from the skill development and self-esteem building that piping and drumming can provide, we now have evidence which indicates that pipe band participation has also had a significant impact on their attainment at school.' Roderick Paisley, a piper himself and Professor of Scots Law at the University of Aberdeen, said the effect could be explained by the maturity and hard work necessary to learn the instruments. He said: 'Pipers and drummers are often more mature, dedicated and hard-working than their peers and they gain personal confidence enabling them to take on difficult tasks and to deal with other people of all ages. Advertisement Hide Ad Advertisement Hide Ad 'The best thing about participation in a pipe band is that all this is learned in an enjoyable way and it sets up pipers and drummers for life.' Preston Lodge was among the first schools in Scotland to benefit from the SSPDT pipe band programme. The high school now has two full-time and one part-time pipe band tutoring staff and runs development, novice juvenile and juvenile pipe bands, with pupils competing in major national and international competitions.
