I am quite embarrassed to say that I got lost in my first solo cross country, but didn't hessitate one bit to contact 121.50
I was mainly nervous, which I think lead to aligning DI inaccurately, and it was quite hazy. My main worry was infringing Luton airspace, and when I saw an Easy Jet with its landing gear down, I knew something was wrong! London info was very helpful and in the end landed safely. Flew the leg back home with no problems despite the adrenaline rush. Luckily didn't fly into Luton CAS, and wasn't too far off track. Should have easily corrected myself with eyeballing inverse ratio method. Lots of lessons learned and didn't put me off navigation. At the end of the day London info are there to help you!
