He completed his first solo on the Vigilant motor glider while on a gliding scholarship with the air cadets. After which, he then stayed on with the gliding school and became a gliding instructor. He then went on to get his professional licence at FTE Jerez before joining a UK regional airline flying the Dash-8 Q400 Turbo Prop. After being stationed at various locations around the UK, he eventually ended up in Glasgow as a Line Training Captain and working for the Flight Safety Department before moving on to flying the 787. His favourite destination is Japan.

He completed his first solo on the Cessna 152 during his PPL(A) at Barton airfield.  He then went on to get his professional licence via the modular route studying at  CAE Oxford Aviation, Bartolini Air and Simtech before  joining an Irish airline flying to destinations all over Europe. He established Ascent Aviation Ltd in 2018 to create a community that  promotes, helps and inspires aviation enthusiasts, young and old from all backgrounds. 

Lisa Callaghan 

Operations Manager

From checking-in for your flight until the final landing, Lisa strives to make sure each and every one of our customers receive a first class experience with us at Ascent Aviation. Lisa graduated from the University of Stirling with a bachelor’s degree in Geography and decided to join Flybe, in 2015, as Cabin Crew. Like many, Lisa caught the flying bug and fell in love with working in the skies. She was based in Edinburgh, flying on the Dash 8 Q400, for over 4 years before she pursued her travelling dream by joining Virgin Atlantic where she was trained to fly on the B787, A350, A340 and A330 from London Heathrow. The Covid-19 pandemic clipped Lisa’s wings and she joined Ascent Aviation as our full-time Bookings & Events Manager where she still loves to deliver a first class service to our customers in the (virtual) skies! 

Tony Clark

Instructor (B737 & A320)

Tony currently flies the Airbus A320 aircraft for an international airline flying both short and medium haul routes. After leaving school he obtained his private pilots license and went on to study aeronautical engineering. Shortly after graduating he moved to New Zealand to complete his professional license through CTC Aviation. On returning to the UK he was offered a flying job and subsequently spent a number of years at various locations around the UK, before finally getting the opportunity to return back to Glasgow, where he is currently based. Tony still has fond memories of his first solo, which was here at Glasgow and despite having flown throughout Europe and the USA and providing the Scottish weather allows, he is still biased towards Scotland when it comes to his favourite views whilst flying.

Matthew McCaw

Instructor (B737 & A320)

Matthew has wanted to be a pilot as long as he can remember, following in his great grandfather’s footsteps who was a Training Captain for BOAC. His mother and grandmother both had spells as cabin crew too so he likes to think it runs in his blood. He had his first flight for his 16th birthday and then moved to Dundee to get his PPL(A) at 18. His first solo was in a Piper PA-28. He then moved to Perthshire to complete his commercial license training and then went out to Dublin to finish the final training course at Simtech. Qualifying in 2021, COVID has meant that Matthew is still waiting for his first airline job but that doesn’t stop him wanting to welcome customers to our B737 and A320 simulators and ensuring each person leaves with a smile on their face. 

Sean Gunn

Instructor (B737 & A320)

Sean started his flying career when he was 23 years old. Having left school with an Engineering eduction, he then pursued his path towards becoming an airline pilot by gaining his Private Pilots Licence at ACS Aviation in Perth. Sean then went on to expand his flying skills by flying all over Poland on the Katana DA20. After returning home to Scotland, he then completed his Multi Engine Instrument Rating and Commercial Pilots Licence at ACS Aviation in Perth. Throughout the difficult times that have came with COVID-19, Sean has continued to show his passion for aviation by delivering a first class flight experience to all customers as one of our full-time instructors who is dual trained on both the B737NG and A320 simulators.

Steve Slater

Instructor (B737)

Steve has been an aviation enthusiast since he was 5 years old which led on to him joining the Air Cadets in 2006. After gaining his PPL from Sherburn, Yorkshire, he then continued his  Commercial training and Instrument Rating abroad in Sweden at Diamond Flight Academy during the Winter of 2019. He is currently employed by a UK based airline in Glasgow on the Boeing 737 and works part time instructing at Ascent Aviation.

Maarten van Leeuwen

Since then, Maarten has returned to the skies operating cargo flights on the B737NG and Classic. When Maarten is not flying from his base airport in Belgium, he works part-time at Ascent Aviation sharing his experience on the B737 with all our customers.
